Take in the breathtaking scale of Cologne's Cathedral (Kölner Dom) with its 43 m high vaulted ceiling, and its 144 m length. Its 157 m spires were originally the tallest structure in the world until the building of the Eiffel Tower.

The most famous Gothic structure in Germany is also unusually complex, whether interms of its splendour, its size or even simply the date of its construction. The foundation stone was laid on 15th August 1248, the presbytery consecrated in 1322. The cathedral was built gradually until c. 1520. It then remained unfinished until the 19th century, when Romanticists revived interest in it. The building was finally completed in 1842-80, according to the rediscovered, original Gothic designs.

Check out the view from the 95 m high viewing platform at the base of the steeple of the Kölner Dom. The 509 steps to the top will work up an appetite. Stop on the way up to see the Peter Bell, at 24-tonnes is the largest working bell in the world.

It's been a UNESCO World Heritage Site since 1996. The main attraction inside the Dom is The Shrine of the Three Magi, a magnificent jewelled reliquary housing the remains of the Three Wise Men.

Top Tip

Following a decision of the Metropolitan Chapter the bell cage stays shut on Sundays and bank holidays until 12.30 hrs. Visitors, who really want to hear the ringing of the bells can get in touch with the Dombauverwaltung, which will in future offer special guided tours of the bells on working days. All visitors will be provided with professional ear protection, without which the visit would be damaging to their health.

The cathedral is open daily from 6am-7:30pm.
