Igreja de São Cristóvão, Colonial church in São Paulo, Brazil

Igreja de São Cristóvão is the surviving chapel of the former Seminário da Luz, on Avenida Tiradentes at the corner of Rua 25 de Janeiro in the Luz district. The two-storey building, begun in 1853 and inaugurated on 9 November 1856, has walls of taipa de pilão (rammed earth) on a 1,440 m² plot with 768 m² built; the upper floor now holds a hotel and the ground floor shops, while the chapel keeps its original use.

The church began in 1853 as the chapel of the Seminário Episcopal do Luz, founded by Dom Antônio Joaquim de Melo; the building was inaugurated in 1856. Its rammed-earth walls collapsed in 1982, leading to interdiction and listing by CONDEPHAAT that same year. Restoration, begun in 1995, ended with reopening on 28 April 2001.

The patron saint is Christopher, whose name means "the one who carries Christ" and who is the protector of drivers. On 25 July, an old tradition holds that anyone who looks at his image is protected for the day, so taxi and truck drivers pass along Avenida Tiradentes in front of the church to receive the blessing.

The church stands at Avenida Tiradentes 84, at the corner of Rua 25 de Janeiro in the Luz district, near the Luz and Tiradentes metro and rail stations. The former seminary building around it now houses a hotel upstairs and shops on the ground floor, so the chapel is reached from the avenue. Visits depend on the Mass schedule.

The church is the only part of the old Seminário da Luz complex still in its original use; the rest of the 1850s building now houses a hotel upstairs and shops on the ground floor. The whole block between Avenida Tiradentes and Rua 25 de Janeiro belongs to the Mitra Arquidiocesana.
