Pre-history Since 2013, excavations have been conducted by the
National Institute for Preventive Archaeological Research (
INRAP in French) in
Vienne where evidence was found of "one or more camps of
Prehistoric hunter-gatherers, who also fished, after fish traps found there. They were
Neolithic farmer-herders, who were present in the area around 6,000
BCE (8,000 years ago).
Ancient times As major urban development begun in 1959, it uncovered the remains of a late Gallic settlement and an urban centre from the Gallo-Roman period. At that time, the town was located on the road linking
Chartres to
Bourges. In the network of cities of the
Carnutes people, Blois was a secondary settlement. Excavations carried out on the right bank between 2001 and 2016 and on the
left bank between 2013 and 2014, it revealed the presence of a large developed town on the right bank and an occupation on the left bank from the Gallic and Gallo-Roman periods. The Loire river has undoubtedly always been a major axis route, although no traces of a port have been discovered. However, there are the remains of former
bridges linking the two banks. The
Robertians were at the head of the county of Blois before 900. When
Hugh the Great became
duke of the Franks, he left the title of count to his faithful vassal,
Theobald I of Blois (
circa 940). His descendants, known as "Thibaldians", remained as Counts up until the county became a royal possession in 1397. The
House of Blois also succeeded in raising some of its members or descendants to the highest levels of the European nobility, notably by acceding to the thrones of France, England, Navarre, Spain and Portugal. In 1171, Blois was the site of a
blood libel against its Jewish community that led to 31 Jews (by some accounts 40) being burned to death. Their martyrdom also contributed to a prominent and durable school of poetry inspired by Christian persecution. In 1196,
Count Louis I of Blois granted privileges to the townsmen; a commune, which survived throughout the
Middle Ages, probably dates from this time. The counts of the Châtillon dynastic line resided at Blois more often than their predecessors, and the oldest parts of the
Château of Blois (from the 13th century) were built by them. In the Middle Ages, Blois was the seat of the
County of Champagne when the latter passed to the French crown in 1314, forming the
province of Champagne within the
Kingdom of France. By 1397,
Count Guy II of Blois-Châtillon offered the county to his cousin,
Duke Louis I of Orléans, brother of
King Charles VI. In 1429,
Joan of Arc made Blois her base of operations for the
relief of Orléans. She rode the 35 miles on 29 April from Blois to relieve Orléans. In 1440, after his captivity in England,
Duke Charles of Orléans (son of Duke Louis I) took up residence in the Château of Blois, where in 1462 his son was born, Duke Louis II of Orléans who would afterwards become
Louis XII.
Renaissance era By 1498,
King Charles VIII died with no heirs in the
Château of Amboise. Subsequently, Duke Louis II ran between the Château and Blois, and was crowned King Louis XII of France. He then married
Charles VIII's widow, Queen
Anne of Brittany, in 1499. The birth of their daughter,
Claude of France, effected the union of
Brittany with the
France. Louis XII, as the last hereditary
Count of Blois, naturally established his royal Court in the city. The
Treaty of Blois, which temporarily halted the
Italian Wars, was signed there in 1504–1505. During his reign, the city experienced a massive redevelopment, with some architectural elements inspired from the Italian
Renaissance, as seen in the medieval castle immediately turned into a
château, and the construction of many
hôtels particuliers for the nobility throughout the entire kingdom. One of which, ''
Hôtel d'Alluye'', was built as a copy of an Italian palace for
Florimond Robertet, who was an important French minister under King Charles VIII, King Louis XII and
King Francis I. On 1 January 1515, Louis XII died. His throne would be passed to Francis I, the husband to his daughter,
Claude of France. In 1519, King Francis I ordered the construction of the
Château of Chambord (10 miles away from Blois), but its construction lasted for one year before he died in 1547. In the meantime, he gradually expressed his will to move to
Fontainebleau, near Paris, and started to abandon Blois. Much of the royal furniture was moved from Blois to Fontainebleau by 1539. The
French Wars of Religion were a significantly destructive conflict for the French people. The city's inhabitants included many
Calvinists, and in 1562 and 1567 it was the scene of struggles with the Catholics. On 4 July 1562, Blois and
Beaugency, conquered by Protestants just before, were looted by the Catholics led by Maréchal de St. André. On 7 February 1568, Protestants under Captain Boucard's command, looted and invaded the town, eventually killing many Catholics.
Grey friars were also killed and thrown in the well of their own convent. In addition, all the churches were ransacked. In 1576 and 1588,
King Henry III convoked the
Estates General to Blois where he attained refuge after an uprising called the
Day of the Barricades. In response,
Duke Henry I of Guise was assassinated on 23 December 1588 for his involvement in the uprising. The following day, his brother,
Cardinal Louis II of Guise, who was also
Archbishop of Reims, suffered the same fate. Their deaths were shortly followed by that of the Queen-Mother,
Catherine de' Medici. In the 16th century, the French Royal court often made Blois their leisure resort.
Early modern era After the departure of the Royal Court towards Paris, Blois lost the status of a Royal residence, along with the luxury and economic activity that came with it.
King Henry IV relocated the Royal library to
Fontainebleau, which would later be the
National Library of France (). In 1606,
Philippe de Béthune gave his ownership of
Vienne-lez-Blois village, on the left bank of the
Loire river, to Blois, making it a part of the city afterwards known as
Blois-Vienne. From 1617 to 1619
Marie de' Medici, wife of
King Henri IV, exiled from the court by his son, King
Louis XIII, lived in the château. By 1622, the
Counter-Reformation arrived in Blois and a
Society of Jesus was founded. St. Louis Chapel, which is today
St. Vincent Church was also built at this time. Then in 1634, Louis XIII exiled his brother,
Gaston, Duke of Orléans and Count of Blois, who became attached to the city. The Duke in 1657, found a hospital in
Blois-Vienne, now named ''Résidence Gaston d'Orléans'', and financed the reconstruction of the
Hôtel-Dieu. He remained in Blois until his death, in 1660. Under
Louis XIV's reign, Blois became an independent
bishopric. David Nicolas de Bertier, first bishop of Blois from 1697, chose as his seat the cathedral church of St. Solenne, that had been destroyed by a storm and was under reconstruction, before being completed three years later in 1700, thanks to the intervention of
Colbert's wife, who herself came from Blois. The new edifice became
Blois Cathedral and was dedicated to
St. Louis. A large episcopal palace was built by King Louis XIV's official architect,
Jacques Gabriel, right next to the newly built cathedral, on a site overlooking the Loire Valley. Landscaping of terraced gardens began in 1703 and lasted nearly 50 years. The so-called Bishopric Gardens were first open to the public in 1791 by
Henri Grégoire (known as the Abbot Grégoire), the first
constitutional bishop after the
French Revolution. During the night of 6-7 February 1716, the
medieval bridge collapsed. Construction of a new one was ordered the following year.
Jacques-Gabriel Bridge was inaugurated in 1724. All the levies were consolidated, and the river channel of
La Bouillie in the prolongation of
La Creusille Harbour was closed and dried. When
Duke Gaston of Orléans died, the château was stripped by King Louis XIV, and completely abandoned, to the point that King
Louis XVI once considered demolishing it in 1788. The building was saved when the Royal-Comtois Regiment established their base within it. In 1790,
Orléanais province was dissolved, the Département of
Loir-et-Cher was created with Blois as the local capital. By 1814,
Marie Louise, Duchess of Parma and wife of
Napoleon I, found refuge in Blois.
Contemporary era There was new development in Blois in the 19th century. Firstly, the railway arrived in 1846 with the inauguration of the
Paris–Tours railway, whose
Blois Station is a stop. The competition with river transport gradually forced
La Creusille Harbour to reinvent its activity. In parallel, the city became more industrialised from 1848 thanks to
a successful chocolate brand created by Bloisian,
Victor-Auguste Poulain. As in Paris, urban organization in Blois was redesigned during 1850 and 1870 by Mayor , who was friends with Baron
Georges-Eugène Haussmann. Riffault ordered the construction of a
boulevard separating the modern upper town (where the cathedral,
Hôtel of Préfecture, and
Halle aux Grains are located), from the medieval lower town. He also paved the way to the construction of the
boulevard Daniel Depuis, in the West of Blois. Between 1862 and 1865, the were built under
La Morandière's supervision, in the axis of
Jacques-Gabriel Bridge and
Blois-Vienne's Wilson Avenue. In the meantime, the lower town faced three of the most significant floods of the Loire river: in 1846, 1856 (the worst), and 1866. The central districts of St. Jean and Blois-Vienne were under water, as well as La Bouillie spillway. On 13 December 1871, the
Prussian Army took control of Blois during the
Franco-Prussian War. The city was taken back by French forces under General
Joseph Pourcet and General . Since then, a memorial stands on Wilson Avenue in Vienne. In 1939, the construction of
Blois Basilica was completed. That same year, between 29 January and 8 February, more than 3,100 Spanish refugees came to the
Loir-et-Cher department, fleeing the
Spanish Civil War and Dictator
Francisco Franco. In June 1940, the German bombings destroyed a large part of the centre, and the French destroyed the 10th arch of
Jacques-Gabriel Bridge to prevent further advance for the enemy. The German army bombed the former Town Hall on 16 June, killing Mayor
Émile Laurens in the process, and took over the city two days later, on 18 June, the exact same day of
Charles de Gaulle's Appeal for
Internal Resistance. Between June and August 1944, US-English-allied bombings destroyed other infrastructures, like the railway bridge between Blois and
Romorantin. In total during
World War II, 230 people were killed, and 1,522 buildings were entirely or partially destroyed. On 16 August 1944, the German troops withdrew to
Blois-Vienne to seek refuge and destroyed the three central arches of
the bridge. On 1 September, they surrendered. The bridge was rebuilt and reopened in December 1948. In 1959, Mayor
Marcel Bühler received President
Charles de Gaulle and launched the construction of the
ZUP, at the North of the city, on the same model of so-called
banlieues of Paris or any other French city. ==Population==
