Swedish limestone paving in 17th-and 18th-century English buildings

Documents concerning buildings by Christopher Wren record the use of Swedish and Danish marble as a paving material. In order to establish the origin of these marbles, original pavings are examined at St Paul's Cathedral and elsewhere. Through analyses of samples and by means of other evidence both marbles are identified as Orthoceras Limestone from the Swedish island of Öland. The stone industry of Öland is described and the import of Swedish stone into England in the 17th and 18th centuries is traced through Scandinavian and English customs accounts.
