The Round Tower
Købmagergade 52A, 1150 København
Spiral cobblestone ramp winding seven and a half times up a seventeenth-century tower to Europe's oldest working observatory.
This guide to The Round Tower in Copenhagen opens with an eyewitness account from October 1716, when Tsar Peter the Great of Russia reportedly rode a horse straight up the tower's spiral ramp while his wife followed by carriage. It traces the conflicting reports of what really happened that day, and the reason King Christian IV built the ramp itself in the 1630s. Above sits Europe's oldest observatory still doing its original work, once run by the astronomer Longomontanus.
