The Sinaia Monastery, located in Romania's Prahova County, was founded in 1695 by Prince Mihail Cantacuzino and named after Saint Catherine's Monastery on Mount Sinai. It is home to 13 Orthodox monks and features two courtyards with Byzantine-style churches. The monastery houses valuable jewels, the earliest Romanian Bible translation, and the tomb of former Prime Minister Take Ionescu. With a rich history dating back to the 17th century, the Sinaia Monastery is a cultural and religious landmark worth exploring.
