Ovčiji Brod is a bridge spanning Zalomka river, which is located in Bratač village, Nevesinje, Bosnia and Herzegovina. It is another masterpiece of Ottoman bridge building in Bosnia and Herzegovina.
The bridge was probably erected in the sixteenth century or even later, but most likely after the Mehmed Paša Sokolović Bridge was built in Višegrad. It's suspected that this bridge was built by no other than the famous Ottoman architect Mimar Hayruddin, who also built the Stari Most in Mostar. The name of the bridge (Sheep Crossing) probably comes from shepherds who used to get their sheep herds across the river by using this bridge.
It is built entirely of stone, it is about three meters wide and its slender appearance, with three arches, irresistibly reminds of the diminished version of the Ćuprija na Drini in Višegrad. Despite its age, and very little restoration, the bridge is well preserved and still used today. The bridge, along with the Kalufi stećak necropolis, was nominated as potential candidates for UNESCO's listing of the World Cultural Heritage.
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.
