The
Church of the Holy Trinity of the Spanish, is an 18th century convent church of Rome in the Campo Marzio, the beginning of Via Condotti, near the Spanish Steps.
For reference, a plan of the church is available
here.
The church and adjoining monastery were built by the Spanish Trinitarians between 1741 and 1746, under
Pope Benedict XIV. The architect was the Portuguese
Emmanuel Rodriguez dos Santos. The interior decoration was completed by the Spanish architect
José de Hermosilla y Sandoval. In 1784, the church and convent came under the direct protection of the Spanish monarchy.
The church underwent the first renovation and upgrades, completed in 1788.
In 1895 the church was assigned to the Spanish Dominicans, who remain in charge. The convent is now described as a Cultural Institution and College of Religious.
