It's the Sveta Gora (Holy Mountain) monastery and the monastery grounds surrounding it. Here is the view from the balcony you can see in the picture, also you can see a statue of Saint Francis of Assisi
Good first gc result for Sobrero.
Interesting how Carboni always seems to be better in his first stage race after the Giro than during the Giro (see occitanie 2 years ago).
Easy win for Pogi, as expected. With him flying from the UAE Tour until LBL a shorter, easier prep race was probably the right call.
