Iglesia San Millán is a fine Romanesque church located outside of the old walls of Segovia. Built between 1111 and 1124, it is one of the oldest churches in the city.
The large church dominates a spacious plaza off of Avenida de Fernandex Ladreda, which leads to the famous aqueduct and passes another Romanesque church, San Clemente.
Patterned closely on the cathedral of Jaca in Aragon, San Millán is especially notable for its pre-Romanesque mozarbic tower and porticoes with abundant Romanesque figurative carvings.
Inside, there are three naves and three apses. The decoration is largely Baroque, but there are some Romanesque frescoes in the chancel.
