The historic centre is located on the former plan of the ramparts. There is a difference between the northern city centre and the southern city centre due to the 1720 fire, which destroyed most of the timber-framed houses in the northern part of the city. The rebuilding was done in stone, on a grid plan. The poorer southern part was not rebuilt.
