History of the building dates back to the end of the 16th century, when it was designed by Antoni van Obberghen, in the style of Netherlandish Mannerism, to be the seat of the Old Town authorities. Throughout centuries it was the centre of contemporary political, economic, scientific and social life of this part of the city. It was here that elites debated about municipal matters, celebrated official ceremonies in Great Hall, and organised balls and banquets. The Old Town Hall is linked to the figure of a famous scientist – astronome Johannes Hevelius. It is him who stored beer in the cellars of the building.
