10. St. Olav Church

St. Olav's Church

Once the highest building in the world (for a period of 76 years from 1549 until 1625), this church still towers over the Old Town and is considered the highest point up to which even new buildings are allowed to be built in Tallinn. The 124-meter tower can of course be climbed, and those who ascend the 232 steps will be rewarded with a truly unforgettable view of the city.
