If you spend time exploring the town of Charlotte Amalie in Saint Thomas you will soon be challenged by its steep hills. The most famous is called Store Taarne Gade, which in Danish means Greater Tower Street, but most people call it The 99 Steps. In case you are counting, there are actually 103. The staircase was built in the mid-18th century using stones that had been ballasts on trade ships. But don’t worry because if you need to catch your breath, there are plenty of historic buildings to see along the way such as the Haagensen House which was built in the 1820s.
