San Domingos Convent was founded around 1282, although the work on the conserved temple did not begin until 1383, continuing through the 15th century.
Following the introduction of the exclaustration law, the convent was closed in 1836. The building gradually deteriorated until it fell into ruin and by 1846 some of its materials were being used to pave streets. In 1864 a chapel was demolished and between 1869 and 1870 the top part of the tower, located on the south-eastern corner, was torn down.
This is the oldest of all Pontevedra Museum’s buildings. The only sections of the original buildings that have been conserved are the main apse, formed by five apses, exceptional in Galician gothic architecture, and part of the south wall of the church and the entrance to the chapter.
References:The Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
