 Cast iron was quickly adapted to allow glass roofs on a wide variety of structures, perhaps beginning with the new glass-roofed shopping arcades of the 1820s in Paris and London, then larger spans (sometimes in combination with wrought iron) such as market halls, railway stations, and department stores.By the end of the 19th century nearly every new market hall in Europe (and most in Latin America) had glass and cast-iron roofs, some vast and elaborate, such as the 1850s Les Halles in Paris (demolished).An interesting application is for a winter garden, with a solid roof but extensive glass walls, such as the Spa Colonnade in the spa town of Mariánské Lázně in Czechia, built in 1889, which features an elaborate roof structure and extensive Neo-Baroque decorations in the facade, all in cast iron.
