John III was very interested in art, especially architecture. He was undoubtedly the most building-minded monarch Sweden ever had. Like his brother Erik, he was highly artistic and aesthetically gifted. However, his sense of beauty found its most obvious expression in the field of architecture. He spent a lot of time drawing up elaborate plans for buildings, only a small part of which were realized during his lifetime. "Building is our highest desire", writes John himself in one of many letters in which he gives orders to his architects and builders.
Foreign expertise called in John called in skilled builders, sculptors and painters from Germany and the Netherlands and also intervened himself, through his own drawings, in the prolific building activity that he provoked in so many places. His surviving letters on building also show that he understood architecture and that he was familiar with the principles of the
Italian Renaissance, specifically the
High and
Late Renaissance. In his letters he advises and admonishes his architects and builders, he corrects their drawings and revels in the details of architecture and decoration. Above all, his interest is focused on the decoration itself: in the exterior on magnificent
portals and windows, ornate
gables and richly decorated
spires, in the interior especially on the rich
paneling and
door frames. , where John settled from 1556 to 1563. He was the only
Duke of Finland to establish a truly independent principality in his duchy. Under the personal supervision of the Duke, the
medieval fortress was transformed into a magnificent
Renaissance palace with wide staircases, large halls and bright windows. In particular,
Sebastiano Serlio's books on the art of building seem to have been a frequent source of inspiration. John's own taste therefore came to assert itself in many ways, and he may justly be regarded as the center of the interesting art movement which arose during his reign. In the large circle of artists and craftsmen around John III there were some more prominent, such as the Swede Anders målare ("Anders Painter"), mostly active as a builder,
Willem Boy, important both as a sculptor and architect (creator of John's tomb in
Uppsala),
Vadstena architects
Arendt de Roy and
Hans Fleming. But John needed more skilled people. Among the foreign masters he employed were the three members of the Pahr family of architects, originally from
Lombardy,
Franciscus Pahr, Johan Baptista Pahr and Dominicus Pahr, the former of whom had his name attached to Uppsala, the latter two to
Borgholm and
Kalmar castles, the
stucco artist and master builder Antonius Watz, the chief builder of Finland and Livonia Peter Hertig, the carvers Markus Wulfrum and Urban Schultz, the painters
Johan Baptista van Uther and Arent Lambrechts, the stonemasons and sculptors Roland Mackle, Peter de la Koche, Lukas van der Werdt and others. Experts from abroad were also called in to help with agricultural matters, including
foresters from the German principalities and Denmark.
Churches and monasteries A particular aspect of John III's interest in building is his concern for the preservation of older monumental buildings. His zeal also extended to care for the appearance of cities. The cathedrals of Uppsala,
Västerås,
Linköping and
Skara were restored to their former glory; in Finland,
Turku Cathedral was restored and given a new
chancel; in Estonia,
Reval (Tallinn) was restored. Among the more or less destroyed monastery churches that were renovated are
Varnhem,
Vreta Abbey,
Alvastra,
Askeby and
Gudhem, and
Naantali in Finland. In Stockholm,
Storkyrkan,
Riddarholmen Church and
The German Church (originally a medieval guildhall which, since it was also given to the Finnish congregation, was long called
Saint Henry's church) were restored, while
The Church of Saint Clare was built on the site of
St. Clare's Priory, which had been demolished by Gustav I. Another new building was
St. James' Church. Other churches he planned, such as a Trinity Church, were never built.
Castles and fortresses John III built
chapels in all his major
castles, with
Vadstena Castle partially preserved and
Kalmar Castle still well preserved. In this
ecclesiastical building activity, the
Gothic traditions, even in detail, lived on. The many castle and fortress projects were partly inherited from the time of Gustav I and Erik XIV, and partly started by John III. The
Tre Kronor Palace in Stockholm was significantly extended and redecorated. The northern courtyard, including the castle church, was given the character it retained until the Castle Fire in 1697. was built in the 1540s by
Gustav I as protection. It was rebuilt by John III. After
Duke Magnus, John himself resided there. The
castle in Uppsala (the present southern part and its western extension) was rebuilt after the fire of 1572 as a brick building with
rusticated
plaster and two round towers. Vadstena Castle, like the previous one founded by Gustav I, was expanded into the
Renaissance palace it still is today, although it was not completed according to the original plan until the early 17th century.
Svartsjö Palace was a curious building, with its circular
arcaded
courtyard and
domed church on either side of an older stone house. At Kalmar Castle, where John often resided there because it was closer to Poland, the perimeter of the courtyard was completed, the floors were laid out on the same level, and in the interior the costly decoration begun under Erik XIV was continued. Borgholm Castle, on the other hand, was Johan III's largest new building, with a completely regular plan, outstanding spaciousness and magnificence, and strong fortifications, but it was not completed during Johan III's reign. Another new building was
Bråborg Castle, intended as a widow's seat for Queen Gunilla, while
Drottningholm (the older one, burnt down in 1661) was built on one of the islands of
Lake Mälaren at the request of Catherine Jagiellon. The rebuilding of Turku Castle,
Västerås Castle,
Gävle Castle,
Stegeborg Castle and
Linköping Castle can also be mentioned. Fortifications were present at almost all the castles. More purely as fortresses were
Älvsborg,
Gullberg,
Kronoberg Castle,
Kexholm,
Vyborg and other places, at which significant fortification work was often undertaken, followed with interest by the king. In the art of fortification, Sweden was at this time at the forefront of the
Nordic countries, because the new
Italian system had been introduced by the Pahr brothers.
Monuments Among monumental works of sculpture, the most noteworthy are the funerary monuments of his father Gustav I and his first two wives, and the beautiful tomb of Catherine Jagiellon, both in Uppsala Cathedral. The monument to John III on the said site was commissioned by his son Sigismund in
Danzig (from the sculptor
Willem van den Blocke), but only came to Sweden in 1782 through
Gustav III's care and was erected in its present location in 1818, albeit with an incorrect arrangement, which was however redesigned by
Agi Lindegren during the church's restoration in the early 1890s. ==Legacy==
