Iglesia de las Calatravas

The Church of the Concepción Real de Calatrava was built in the historic center of Madrid in the late 17th century by Fray Lorenzo de San Nicolás, an Augustinian monk and accomplished architect. The church has the earliest dome constructed with the encamonado technique, which consists of a wood structure with a brick infill, a technique that continued to be used in Madrid until the early 20th century. The façade was designed later by Juan de Madrazo y Kuntz. José de Lara Churriguera built the main altar and two smaller side altars in the interior of the church.
