St. Martin's Cathedral by Ewingjr98
St Martin's cathedral is considered Germany's second most important catholic church, with Cologne's Dom being first. Originally a Roman-style basilica, built in 975 AD, the church reached its current form in the 13th and 14th Centuries. The oldest part of the church is the crypt, dating back to the origins of the structure, over 1000 years ago.
