From Bucharest we did a day trip to northern Bulgaria. We visited the Rock Hewn Church of Ivanovo. These churches were carved by Orthodox Monks. There are 5 such historical sites and we only visited one of them.
We then visited Veliko Tarnovo the capitol of medieval Bulgaria during its second Empire. Of note here is Tsarevets Fortress. A huge defensible position as it is almost completely surrounded by the Yantra river (it's worth looking at it on Google Maps, that river was completely drunk). The fortress is connected to the main town by an old stone bridge.もっと詳しく

so they carved this chamber out of rock... was it sandstone? or something harder?
