San Miguel Arcángel was built in the late 17th century in the colonial Baroque style, but in the 19th century, a local builder Zeferino Gutiérrez Muñoz was asked to rebuild the towers and facade that had suffered substantial cracking over the years. He was a bricklayer by profession and so he relied on a postcard of Cologne Cathedral in Germany for inspiration. The result is a massive pseudo-Gothic structure that has become the iconic emblem of San Miguel de Allende, 50 miles west of Querétaro.
