The buildings of the former collegiate church of St Martin’s chapter, which are completely gone today, is a Catholic parish church today. A three-nave transeptless pier basilica with as straight-ended choir in 12th-century architecture, St Martin’s once was until the 15th century the tomb of the influential Kämmerer family, also known as the von Dalberg family. Legend has it that there was a dungeon in the basilica where St Martin was incarcerated.
According to tradition St Martin’s church was founded by Emperor Otto III during Bishop Hildebold’s reign (979—998). The first evidence of the chapter is given by a charter from AD1016, but the buildings were still incomplete in 1025, when Bishop Burchard died.
St Martin’s church was until the 15th century the burial site of the Kämmerer family, also known as the von Dalberg family, whose estates where situated in the neighbourhood of the church, in today’s Kämmererstraße (tombstones).
The chapter’s buildings (north of the Church) were altered considerably when the complex was reconstructed as an infirmary in 1891. Of the cloisters, first mentioned in AD1269 and extended in AD1290, some of the Gothic arcades in the northern and western wings are still preserved (in the latter they are concealed by mortar).
