The Saint Sebastian Church or Iglesia de San Sebastián is a 16th-century church in central Madrid Spain. It is located on Atocha street #39. The name arises from a devotional chapel (ermita) which was found along the route to the Basilica of Nuestra Señora de Atocha founded in 1541. The first architect around 1550 was Antonio Sillero who also finished the Chapel of the Sagrado Corazón.
