Martinitoren
Over 250 steps
Because there is no lift, climbing the d’Olle Grieze – Old Grey One – involves some unremitting labour. Most visitors take about an hour for their visit. But rest assured that your work-out will be handsomely rewarded. After every so many steps, take in the Martinikerk church vaults, centuries-old ornaments, heavy bells or giant flagpoles. On the first gallery, step outside to walk around the tower at a height of 39 metres.
