Relics of a Medieval wall paintings were found during architectural studies and conservations of the basements of the historic town hall in Gdańsk in Northern Poland. The most significant painting depicts Christ in a scene of crucifixion. The discovery was made in a chamber that was used for collecting taxes in the Medieval times. This part of the historic building is one of the best preserved Medieval secular interiors in Gdańsk.
The discovery was made after removal of cement plaster that was used to cover the walls in order to repair destructions made during World War II. The painting was hidden under that layer of plaster. The historians knew that there was a chapel in the town hall somewhere, as the Papal bull of 1427 allowed for creation such a place in the town hall, but they were unable to pinpoint it so far. It was suspected that it could have been located in the Great Hall of the City Council. This new discovery suggest a new location, but nothing else seems to support it. The painting is currently under conservation and said to be opened for public in future.
