La Santísima Church is located at the corner of La Santísima and Emiliano Zapata streets. Its full name is Temple and Hospital of the Most Holy Trinity (Templo y Antiguo Hospital de la Santisíma Trinidad). The church was built between 1755 and 1783 as a temple for the adjoining hospital/hospice for priests. The church still retains its original function but the adjoining hospital and office sites have since moved into private hands with only parts of the original structures still intact and preserved. The church is also noted for the fact that it has sunk almost three meters since it was built.
