Fodor's Expert Review Basilika St. Martin

First mentioned in 793, Basilika St. Martin was built on the site of a Roman temple. It's been destroyed and rebuilt a number of times since then and as a result is an interesting mix of architectural styles; the 11th-century crypt and Gothic and baroque furnishings make it worth a visit. It's a ten-minute walk from here to the 12th-century Drususbrücke, Germany's oldest medieval stone bridge, which runs over the Nahe.
