Rententurm Main, Frankfurt, Guia do visitante e o que fazer por perto

Only three towers remain from the medieval fortress that once ringed Frankfurt, and the Rententurm is the best preserved. Built in 1454-1456, its stone foundations rest on walls from Emperor Frederick Barbarossa's palace in 1150. That means 800 years of history stack in this single tower. Medieval merchants paid customs duties at this gate to enter the port; power and commerce intersected here. Now part of the Historical Museum, you can walk through layers of time. A Questo city game leads you through Frankfurt's transformation from medieval fortress city to modern metropolis.
