Finding Alexanderplatz is no problem: just head toward the 1,207-foot-high tower piercing the sky. Built in 1969 as a signal to the west (clearly visible over the Wall, no less) that the East German economy was thriving, it is deliberately higher than both western Berlin's broadcasting tower and the Eiffel Tower in Paris. You can get the best view of Berlin from within the tower's disco ball–like observation level; on a clear day you can see for 40 km (25 mi). One floor
above, the city's highest restaurant rotates for your panoramic pleasure. During the summer season, order VIP tickets online to avoid a long wait.
