The Fethiye Mosque is located on the northern side of the ancient Roman Agora in Athens and was built on the ruins of a Christian basilica from the middle Byzantine period (8th/9th centuries). The Christian church was converted into a mosque in 1456/58, soon after the Ottoman conquest of the Duchy of Athens, to coincide with the visit to the city by Sultan Mehmed the Conqueror in 1458.
Only a fragment of the mihrab survives from this mosque, which was demolished and replaced by the present structure between 1668 and 1670. The new mosque comprises a porch and a large rectangular main hall, crowned by a dome supported by four pillars. The central dome is flanked by half-domes on each side, and by smaller domes on each corner. The porch is supported by five arches, each crowned by a small dome, resting on masonry on the sides and four pillars in the middle. During the brief occupation of the city by the Venetian forces in the Morean War (October 1687 – May 1688), the mosque was converted by the Venetians into a Catholic church, dedicated to Dionysius the Areopagite.
Following the outbreak of the Greek War of Independence, in 1824 the disused mosque was used as a school by the Filomousos Eteria of Athens. At about the same time, or shortly after the end of the war, the mosque's minaret was torn down. From 1834, after Greek independence, and until the early 20th century, it was used successively as a barracks, a military prison and finally as a military bakery, at which point additions were made to the building to house the bakery's kilns. From the early 20th century it is used mostly as a storage place for various finds from the excavations in the Agora and the Acropolis of Athens.
Except for the removal of recent additions and the restoration to its original shape in 1935, the mosque has never undergone a complete restoration, and by 2010 had developed serious structural problems. In autumn 2010, the Greek Ministry of Culture ordered the emptying of the building from the various antiquities stored there, and the beginning of the process to restore it and open it to the public. Today it is open to the public.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.
