Fortress Toplitsa is a late antique and medieval stronghold situated on the peak of Hisarya Hill above the village of Mineralni Bani in Bulgaria. The site features the remains of a fortified circuit wall enclosing a plateau that served as a strategic observation post. Archaeologists have identified structural layers dating back to the Roman period, which were significantly reinforced during the Byzantine era and the Second Bulgarian Empire. The fortress overlooks the thermal springs of Mineralni Bani, a site known for its healing mineral waters since ancient times. Visitors can observe foundations of defensive towers and domestic dwellings scattered across the summit terrain. The fortification played a critical role in controlling the movement through the valley connecting the Thracian Plain to the Rhodope Mountains.
The highest point on the northern ramparts offers the best panoramic view of the village and the thermal water park below.

Attempting the climb in wet weather, as the rocky trail becomes slippery and dangerous.
