Fort Kosmač was the southernmost fortress in the Austro-Hungarian Empire, guarding the southern extremity of the border between the empire and Montenegro. It is situated near Brajići village, on a hilltop overlooking the road between Budva on the coast and Cetinje, the Montenegrin capital at the time. Constructed in the 1840s, it was attacked during an 1869 rebellion and was garrisoned by Austrian troops until the fall of the empire in 1918. After passing to the newly established Yugoslavia, it was garrisoned again by Italian troops for a period in the Second World War.
The fort is now in a ruinous condition; it once had three storeys, but the topmost storey has collapsed entirely, leaving it roofless. The interior walls, floors and central staircase have also collapsed. Although the remains of the main staircase are still visible, the steps have disappeared entirely and the upper level cannot be reached, though there is nothing left of the upper floor to stand on in any case.
The interior of the fort is strewn with large quantities of fallen masonry, completely obscuring the original floor level. The extent of the collapse is so complete that it is no longer known how the interior was originally laid out. There are substantial holes in the interior's vaulted ceiling. The exterior has been subjected to some stone-robbing in pursuit of the finely-worked square blocks of grey limestone that were used to line the fort's outer walls.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
