Strong medieval fortification tower Kiek in de Kök (Germ. "peek in the kitchen") got its name from a legend about some soldiers in the tower who liked to peek from the top of the tower into the windows of Lower Town kitchens.

The café on the fifth floor affords one-of-a-kind views of Toompea, the Lower Town and the harbour.
