St Aubin's Cathedral (1751-1767) is the only cathedral in Belgium built in academic Late Baroque style. It was the only church built in the Low Countries as a cathedral after 1559, when most of the dioceses of the Netherlands were reorganized.
In the interior, there is an ornamented frieze, carved with swags of fruit and flowers between the Corinthian capitals runs in an unbroken band entirely round the church. All colour is avoided, replaced by architectural enrichments and the bas-reliefs in the pendentives of the dome. The interior contains some pieces of art, like paintings by Anthony van Dyck, Jacob Jordaens and Jacques Nicolaï, a Jesuit brother and student of Rubens. The is also an old, romanesque baptismal font.
In the cathedral a marble plaque near the high altar conceals a casket containing the heart of Don Juan of Austria, Habsburg governor of the Spanish Netherlands, who died in 1578; his body lies in the Escorial near Madrid.
Despite being in Belgium, the cathedral design has an Italian influence; it was built to designs of the Ticinese architect Gaetano Matteo Pisoni in 1751 and 1767. A tower of the former Romanesque church dated from the 13th century that stood on the site has survived and is located at the west end of the church.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.
