It's best to know what Roussalka activities you'd like to do when you visit Roussalka, Bulgaria. But if you haven't planned beforehand, here are some possible Roussalka activities which could include visits to a number of Roussalka attractions:
Aladzha Monastery is one of the 120 medieval rock monasteries close to the seaside that are rapidly becoming tourism hubs in their own right. The monastery was founded during the Second Bulgarian kingdom, around the 13th century, and inhabited by hermit monks. It is located in the beautiful lush woodland of the Franga Plateau in the Golden Sands National Park. Aladzha Monastery was opened in 1906 as a museum and tourist site, and was declared a national monument of culture and antiquity. It also houses a church, a smaller chapel, monastic cells and a small museum that exhibits its colourful history. Aladzha (meaning multi-coloured in Turkish), due most probably to the bright colours of its wall paintings, contains rooms carved into the rocks on two levels in the almost 40-meter high limestone rock connected via an external staircase. The lower floor hosted the monks' private cells, common rooms (i.e. kitchen, dining room) and a small church, while the upper level was dedicated entirely to a chapel. According to some historians, primitive monks' cells were built and inhabited already in the 4th Cent AC. The monastery is considered to date back to the 12th century AC. The monastery is decorated with religious frescoes, but unfortunately most of them are damaged today. There are a lot of legends about unknown tunnels and labyrinths within the rocks where great treasures lay hidden. The monastery was declared a national record, and in 1957 it became a monument of culture. The Catacombs is located 800 meters southwest of Aladzha Monastery - and is a group of monks cells (caves) on 3 different levels in the cliff. Catacombs caves share a similar history to those of Aladzha Monastery, but have suffered even more by the passage of time, being in an even worse state that the relatively well preserved monastery. Archaeologists have found pottery and coins there that prove that the Catacombs were inhabited in the Early Christianity period between the fourth and sixth century.
