Located on the Osława River just 6.5km (4 miles) south-east of Sanok, on the way to Ustrzyki Dolne (32km/20m away), the sleepy little town of Zagórz is an easy diversion between the two, even if you're travelling by train.
The small town's primary attraction is the Monastery of Discalced Carmelites, which comprises an area of 1.75 hectares atop Mariemont Hill. Dating from the 1700s, the complex is a rare example of a fortified monastery and was the site of the last battle of the Bar Confederation, resulting in its destruction during a siege by the Russian Army. Today a ruin, the complex's remnants offer a fun outing for urbex explorers, and one of the observation towers has been rebuilt, providing fine panoramas of the surrounding region.
A recreation of a monastic garden with paths and informational placards has been established next to the ruins, and an adjacent building also now houses the Foresterium Culture Centre, where you can check out the site as looked in the 18th century via virtual reality glasses, while also getting a multimedia rundown of the site's history.
