The White Fortress (Bijela Tabija) is an old fort overlooking the historic core of Sarajevo. It is a protruding part of the wall of what was historically known as the old Vratnik City, and dominates the Eastern, the natural entrance to Sarajevo. It is built of stone and it used to house a gun-crew and an ammunition storage. Its thick walls have openings for cannons.
As far as the precise year of construction goes, differing opinions have been put forward. One of them proposes that Bijela Tabija was built around 1550 (this opinion is founded on the information given by the travel writer Katarino Zeno) and was destroyed during the time of Vratnik City's construction when a new fort was erected in its place.
According to another opinion, a fortress existed in the place of Bijela Tabija during the Middle Ages and it was not bigger than the usual medieval defence fortresses that protected open settlements in their vicinity. Since it is confirmed that there was a medieval settlement Tornik on the site of today's Sarajevo, it is safe to presume that this settlement must have had a fort which protected it.
Bijela Tabija's location which overlooks the entire Sarajevo valley is ideal for situating a mediaeval fortress. It was a fortress with a rectangular base, accompanied with four square-based towers at each of its corners and a fifth above the entrance gate. This shape classifies it as a building from the late 14th or early 15th century, which is exactly the time when the medieval settlement on the site of today's Sarajevo is first mentioned in written documents.
Prior to the Bosnian War of the 1990s, devastation inside the Bijela Tabija complex were the result of poor maintenance which caused the decaying and destruction. Furthermore, the site was endangered by stealing of its construction material (stone) and illegal housing in the contact zone caused the additional demolition of ramparts and surrounding area. During the several years of war Bijela Tabija was exposed to direct shelling of heavy weaponry.
Plans for a project of structural repairs, preservation, restoration and revitalization of Bijela Tabija to active use of this area are under way. Their goal is to establish Tabija as the permanent destination of Sarajevo's art scene and to include it as a tourist attraction which includes exhibition halls, shops, inns and various tourist businesses.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
