The former Ursuline Convent has been well-preserved, with the interior especially having almost no subsequent modifications. The current monastery complex was rebuilt from the original Renaissance building, whose remains are still partly preserved in the brickwork, after the great fire of 1709. The monastery was built in the Baroque period as a two-storied yet unfinished building complex around two central courtyards. There are still a number of vaulted rooms in the interiors. In the former refectory there is a preserved stucco ceiling with murals. In the nineteenth century, the monastery complex was extended by a further wing in today's Křivá Street.The Gothic Church of St. Catherine is the most valuable object in the monastery. It was built before 1287, together with the original Dominican Convent. Dominican nuns occupied the Convent until 1782, when they were superseded by the The Ursulines. The Dominican convent was the last of the early medieval monasteries built in the city.
The Church of St. Catherine was rebuilt in 1362, perhaps by the bishop's building works, which had previously worked on the construction of the Church of St. Maurice in Kroměříž. From this time originates the vaulting of the rectangular end of the presbytery. Some adjustments took place in late 14th and early 15th century, according to shapes of some of the window traceries. During the Renaissance, the western Gothic portal of the church was equipped with an imposing door decorated with a rich ornamental carving. The portal itself originates from around 1400. A Baroque coat of arms of Count Albert Friedrich Vetter of Lily is placed above it. The Convent church was also hit by the devastating fire in 1709. The nave had to be vaulted over with a new groin vault at that time. Another fire in 1800 destroyed the roof of the church and a new roof was built. The church interior underwent the last adjustment, a re-gothization, in the years 1848-1884. In 1987 a restoration of the facade took place, during which the original Gothic windows with stone tracery have been uncovered.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
