Monforte de Lemos is a city and municipality in northwestern Spain, in the province of Lugo, Galicia. It covers an area of 200 km² and lies 62 km from Lugo. As of 2017 it had a population of 18,783.

Nosa Señora da Antiga's School, a monumental school and church in Herrerian style, is known as the "Galician Escorial". The square in front of it was known as Campo da Compañía ("The Society Square") when the building was occupied by the Society of Jesus, which managed the school until their expulsion order from Spain, after which the Piarists took it over.

Important sights include:

• Nosa Señora da Antiga's School
• Inside the school's church is an altarpiece built by Francisco de Moure and finished by his son. Over the altarpiece is an empty piece of wood from which the Society of Jesus' symbol was erased, in order to clean every fingerprint they left on Spain. The school also houses a collection of pictures by artists such as El Greco and Andrea del Sarto. The monumental stair, featuring an apparent lack of physical support, is made from one marble piece, and supported on air by a game of strengths. The praying statue of Cardinal Rodrigo The Castro is placed over his grave, inside the church, and in front of an image of Nosa Señora da Antiga; recent works have found that the grave of Cardinal Rodrigo's mother is hidden behind the picture.
