While in Cologne, you can visit Germany's oldest city hall, with parts dating back to the 11th century. Over time, it has picked up a mix of styles—Gothic tower, Renaissance loggia, some modern touches. The 61-metre tower is covered in carved figures, including some cheeky ones from local history, and the bells chime four times a day. There’s also a mechanical face called the Platzjabbek that sticks its tongue out on the hour. Inside, the Hansasaal is the main historic hall—worth a look if it’s open.
