The Old Father's Hospital (Hospital de los Venerables), also known as the Priest's Hospital, is a 17th-century baroque church located in Santa Cruz. Originally the residence of the old priest, it is now the center of the famous Spanish painter Velazquez Research Center. It was listed as a cultural heritage on December 31, 1970. Built in 1676, the ceiling of the Holy Collection Room is a small space that uses visual trapping techniques.
