Studies of the construction have proved that the town hall was located at the same place in the 13th century. The 600-year-old building was built upon the old town hall's brickwork. A stone building was there in 1250. A building with a meeting room (
consistorium) and a basement () is mentioned in 1322. As the town grew richer and more powerful, it was rebuilt. At the end of the 14th century, the building was as tall as it is now, but it was narrow and without the tower. Only the arcade-gear, which differed from the current one, referred to the fact that it was not an ordinary
dwelling house. The major work began at the beginning of the 15th century. The town council celebrated Easter of 1402 in the old building. The construction started right after the holidays. The leading master of the building was probably stonemason Ghercke. It is possible that the leading masters, including Ghercke, came from downtown
Toompea, where extensive works had ended in the last quarter of the 14th century in the fortress, the circular wall of Great Toompea and in the cathedral (). 600 logs, 581
balks, 46 pairs of
girders and 107 burdens of stone were brought to the construction site. The stones were brought from
Lasnamäe, where a stonemasons village was located. The names of the carriers have been documented. Crude stones were brought for the bricklaying, but some of the details had to be made of cut stone. The main construction – foundations, walls and vaults – was built out of limestone brought from the limestone plateau, limestone brought from stone pits near the city and all put together using lime mortar. In 1403, the stones were cut and an arcade, pillars supporting the vaults, window jambs, etc. were built. The smaller southern portal of the cathedral () was used as an example. The construction works continued later: the roof and a tower were repaired, the windowpanes and staircases were changed and the ovens were set. The Golden Age of the historical Tallinn was a period from the middle of the 15th century to the beginning of the 16th century. The economical prosperity of the Hanseatic times made architecture and artistic creations possible. The vane Old Thomas was established above the town hall in 1530 (the current vane is its exact copy; the initial vane is in the town hall's basement and the vane from 1996 is in the city museum ()). Heinrich Hartmann, who was from a well-known molder family, prepared a bell for the town hall at the end of the 16th century. In the 17th century the town hall got a new spire that was made by master builder Greiger Graff. Formerly, there were no
rain deflectors that would reach the ground. The dragon-headed gargoyles from stone or iron were on the eaves instead of these. They had to lead the water away from the building. The
coppersmith Daniel Pöppel hammered dragon-headed gargoyles from the copper-plates simultaneously with finishing the tower. The tower's wooden structure that had been restored in 195, was partly rotten by 1996 and the tin coating was broken. So, the spire and the Old Thomas with a symbolic meaning were both replaced. The Old Thomas could have fallen down in case of a bigger storm. The works began in the beginning of 1996, when the needed details were prepared in
Albu parish. The parts of the tower were transported to Tallinn in June – the assembly and covering with copper tiles had already begun. It took 1.4 tonnes of copper plates to cover the wooden structure of the tower. In the last week of work on Wednesday, the tower's parts were put together and initially, the Old Thomas was placed on the tower next to the town hall tower. The old tower had to be strengthened so that it would not decay during the work. The upper part was raised at 8:45 a.m. Initially the work was planned to be finished at 3:00 p.m but was delayed until night. The wind rose and when only the last part of the tower was left to be raised, there was a risk that the wind would disturb the work. Finally, at 7:00 p.m., the last part of the tower was taken to its place. The tower's construction and placement were worked out by the project office Sille, engineer Danil. Plans were carried out by AS Stinger, led by Voldemar Metsaallik. The spire was put up with the help of
Pekkaniska aerial platform. During the restorations in 1970, one huge medieval hall was restored. It had been rebuilt as smaller chambers for over 300 years. The ovens' two
foot chimneys that were built to heat the chambers were demolished from the hall to the vaulted ceiling. The hole in the vaulted ceiling that was hacked there in the 17th century was covered with a plastered wooden base hanging on the ropes. In 1996, the Old Thomas might have lost his sword when the old tower was lifted down. The Old Thomas' fastenings were almost completely unfixed and the water dripped from the tower sphere underneath the vane. Apparently, the sword could have fallen down with a storm on the town hall's roof or ended up in the house of a souvenir collector. In Tõnu Lauk's opinion, the Old Thomas decayed quickly because in 1952, the statue was left unpainted. In addition, nothing was done to prevent the rusting of fixing details. In addition, the wooden structure was built improperly. Water flowed in and the tower rotted quickly. During the construction of the new tower and a vane, these mistakes were kept in mind. Old Thomas was primed with red tin, painted and partly
gilded. The light-green vane is allegedly exactly the same as the original. Old Thomas' face, neck, feet, sword, flag and the tower sphere on which the statue stands are golden. It took about four grams of golden plates for all of this. The change occurred in 1992 from architect Böckler from AS Vana Tallinn. He stated that complete gilding was not common before. The first Old Thomas from the year 1530 was also partly gilded. The original of Old Thomas and the dragon-head-shaped
gargoyles that are also partly gilded confirm that saying. Letters written to the town council and aldermen from the 14th–16th centuries, medieval firefighting equipment, tools, revolutionary leaflets from the year 1905, and more are on display. Most of the elements of the interior decor were not thrown away as the town hall's architect back then – Böckler – thought that they were a nice, complete and dignified part of the interior. In addition to the citizen's hall furniture, carbon black polyester lacquer partition doors called piano doors, which were very fashionable at the time and are in harmony with the other black elements of the interior, remained. The director of the town hall, Elviira Liiver Holmström, said that in addition to being restored, the town hall was partly reconstructed. Because of this, the town hall kitchen got back its casing pipe, which was once demolished. The chimney is partly a stairway where a spiral staircase leads to the attic. The attic was cleaned of dust and renovated and has become a museum and place for exhibitions. In 2003, on 17 April, a huge piece of chimney from the 17th century that had been found while excavating the layer of rubbish in the attic fell through the big hall's ceiling; the hall was closed to events until 5 May. According to Böckler, the human-height piece from the fireplace stayed untouched during the restoration works in the 1970s. Two-metre high parts on the foot chimney were cleaned during the excavation of the Town Hall's attic. The brick lost its support from friction and relied on the wooden cover of the vaulted ceiling, of which the rope broke at night. At the moment of the accident, there were no people in the room. In 2008, a medieval well and different models were found under the floor. The accounting room located on the second floor that had been the aldermen's workroom – and from the end of the 19th century until the 1970s the mayor's cabinet – was innovated in the same year. Tallies from the 16th and 17th century were copied, the copies were exhibited and the whole room was redesigned. In 2009, Tallinn Town Hall underwent repairs for two months from February to March and the building was closed. Major repairs were planned. Initially there were plans to make floor repairs and large renovations. Floor tiles from
dolomite were planned to be replaced with
limestone. In addition to excavation, an underground drainage was planned to be opened to examine its condition; in addition, the expected findings were intended to be exhibited. Due to the lack of money, the scale of the project declined. Repairs were done in the basement hall, but events were not held in the upper hall due to the construction dust and noise. The walls of the ceiling had become friable to the touch and had started to decay. The ceiling in the basement was cleaned from the hatched and dirty latex colour and whitewashed. In addition, repairs were made in the staff room, which was given new furniture and lighting, as the rooms were too dim before the repairs. == Tower ==
