made during a 2010 archaeological campaign, realized prior to the launching of reconstructions linked to Bydgoszcz Urban Revitalization Plan. These excavations unveiled well-preserved foundations of the former gothic town hall (e.g. vaulted cellars) once standing in the middle of Old Market square, basements of the town hall tower and merchant stalls. In addition, traces of settlement dating back to the 12th century and elements of Iron Age Pomeranian culture period have been found. Jagiellonian period (1346–1772) The original buildings of the Market Square were made of wood. Residential brick buildings do not appear before the 15th century. The Gothic brick edifices from the end of the 15th century were expanded with Baroque features in the 17th century and rebuilt at the beginning of the 20th century with Eclectic and Art Nouveau façades. The oldest element preserved in the vicinity of the Market Square can be found at the back of the house at Farna Street 6: it is a stone tablet with a Latin carving, displaying the date (1593) of the building and the initials of the owner -Bartosz Krąpiewski-, city councilor and mayor of Bydgoszcz between 1599 and 1603. Presumably, the first town hall, made of wood, was built in the 14th century at the centre of the market place. During the following century, it was replaced by a Gothic brick edifice. After its burning in 1511, a construction of a new town hall started, according to the design of master Jan from Gdańsk. It was completed around 1600, and featured a Renaissance high building with a tower, which was the pride of the city. Documented sources report the start of a construction in 1523 of a water supply network in the city, thoroughly modernized after 1541 by pipe-master Walenty from Bochnia. Wooden pipes were laid on the surface of the Market place and four public water wells built, probably connected with waterworks. During the second part of the 17th century, together with the downturn and depopulation of Bydgoszcz, the water supply network was neglected, but it partially fulfilled its role until the 19th century. At the beginning of the 17th century, at its heyday before the Polish partitions period, chronicler Wojciech Łochowski described Bydgoszcz as follows: "The whole city is girdled by a wall, there is a high tower at the forefront of the market, from 1600, neatly set, and the town hall is decorated with brick.
