The Church of San Gil is a Gothic church built between the 14th and 16th centuries and is considered as one of the most beautiful Gothic churches in Burgos. The church is located at Calle San Gil, 12, beside the medieval wall and it has a simple facade. The church has three naves and there are many funerary chapels in the church. The tombs are excellent examples of Gothic and Renaissance funerary art. The Nativity Chapel has a starred vault and an impressive Renaissance altarpiece. The Chapel of the Good Morning (so called because of the early hour that the priests say Mass) has an excellent Gothic altarpiece, created by Gil de Siloe. Legend says that Santa Teresa used to hear Mass here. The third interesting chapel is the Chapel of the Cross that was created by Juan de Vallejo in the 16th century.
