Of the church spires that are Zürich's signature, the Fraumünster's is the most delicate, a graceful sweep to a narrow spire. It was added to the Gothic structure in 1732; the remains of Louis the German's original ninth-century abbey are below. Its Romanesque choir is a perfect spot for meditation beneath the ocher, sapphire, and ruby glow of the 1970 stained-glass windows by the Russian-born Marc Chagall, who loved Zürich. The Graubünden sculptor Alberto Giacometti's
cousin, Augusto Giacometti, executed the fine painted window, made in 1930, in the north transept.
