The manor of Ekolsund was established in the 1300s. The first known owner was the council Magnus Knutsson, mentioned in 1351. In the 1500s the castle came into royal hands when King Gustav Vasa took over the ownership. It was in 1578-1611 the residence of Princess Sophia of Sweden.
The crown anyway donated Ekolsund to Åke Tott in 1618. Ekolsund was moved again to the Crown during Karl XI’s reduction, and in 1716 it was appointed to Landgraf Fredrik of Hessen-Kassel (later Fredik I). In 1747 it was sold to Prince Adolf Fredrik on the account of the new heir Gustav (later Gustav III). In 1785, Ekolsund was sold from the hands of the Crown to George Seton, a man of Scotish heritage. In 1917 it was bought by Carl Kempe. In 2002, Ekolsund was bought by a private firm.
Both southern and northern castle was built in the middle of the 1600s, excedran came centuries later. Architects were Simon de la Vallée, Nicodemus Tessin the Elder, Carl Harleman, Carl Fredrik Adelcrantz and Jean Eric Rehn.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.
