Göksholm is the oldest privately-owned building in Sweden that has been continuously inhabited.
In the middle ages Göksholm was just a fortified castle with a large tower. Its oldest existent parts have been dated to the 13th century. It was built (rebuilt and enlarged) during the Middle Ages through six different stages.
After a fire at the end of the 16th century, the building was modernized according to that period's style, getting a more regular plan, bigger windows and details in the Dutch renaissance style. Despite the thorough renovation, the medieval base structure remains. A painted inner ceiling from the time of this renaissance renovation exists with 121 cassettes which is remarkably well preserved today.
Under the 17th century owners, Baron Knut Kurck and Baron Fleming, the castle was encrusted with portals, and circle-patterned outer buildings. Lars Gustaf Tersmeden had the ceiling renovated in 1801. This was the last big change in its structure. Some facade details were changed in the 1950s.
Historically Göksholm is famous for the popular uprising's leader Engelbrekt Engelbrektsson, the leader of the government, having been murdered on its lands in 1436 by Måns Bengtsson, the son and heir of the then owner of the castle.
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.
