Massive!

While John was at work I visited Cologne Cathedral. It is massive! A peaceful, if cold, place with a wonderful mosaic floor.

Wikipedia says 'It is a renowned monument of German Catholicism and Gothic architecture and is a World Heritage Site. It is Germany's most visited landmark, attracting an average of 20,000 people a day.

Cologne Cathedral was built between 1248 and 1880. It is 144.5 metres (474 ft) long, 86.5 m (284 ft) wide and its towers are approximately 157 m (515 ft) tall. The cathedral is the largest Gothic church in Northern Europe and has the second-tallest spire and largest façade of any church in the world.'
