Belogradchik Fortress, also known as Kaleto Fortress, is partially built into the Belogradchik Rocks. These rocks were formed 200 million years ago. The original fort dates back to when the Roman Empire was invading Europe and establishing settlements.

During the 14th century, the Ottoman Empire occupied the remnants of this fortification, reinforcing the structure and adding tunnels and walls. The stone fortress is one of the most ancient structures in Bulgaria and contains elements of Roman, Ottoman, and European architecture.

The fortress was used as a military base in 1885, during the Serbo-Bulgarian war, and then abandoned. Today visitors can enjoy a hike up the rocks and visit the open-air museum. There are three walled courtyards and defensive bunkers, as well as rock stairs and wooden ladders that visitors can climb.

Babini Vidini, Kuli Fortress as it is also known, is the only fully preserved castle in Bulgaria. This is the oldest fortress in the country and is built on the ruins of the ancient town named Bononia. The last Bulgarian King, Ivan Sratsimir ruled from this castle until it fell under the rule of the Turks.

This excellently preserved fort is still surrounded by a moat which transports you back to a time when you can almost see the invaders attempting to cross the moat to invade the stronghold. The fortifications, consisting of two concentric circles, are towers separated by curtain walls.

Visitors to the fort can explore two of the eight towers and see weapons that were used during attacks from the Ottomans. Tour the dungeons and view the torture equipment used in the Middle Ages.

Cherven Fortress became the seat of the Bulgar Orthodox Bisphoric of Cherven in 1235. It was the centre of the military, administration, and cultural activity for north-eastern Bulgaria.  Although the fortress only dates back to the 14th century, archaeologists have discovered evidence of inhabitation in the area of Cherven dating back 2000 years.

Invaded by the Ottomans in 1388, the fortress was totally ransacked and left in ruin. The only structure that remained was the 40-foot tower which still stands today.  The original fortification was an elaborate construction that consisted of an inner town with skilled craftsman guilds such as ironworkers, goldsmiths, pottery, baking, and more.  It was well known in the region for its excellent craftsmen.

Today visitors can see excavations that include thirteen churches, a feudal palace, houses, streets, and workshops where the craftsmen would have made and traded their wares.

After spending a summer in the area, Queen Maria Alexandrina Victoria de Edinburg of Romania commissioned Italian architects to build her a summer residence that overlooked the Black Sea.

This eclectic complex was built between 1924 and 1927, when Balchik was still part of Romania. Every possible need of Queen Marie was met, which included her personal minaret built next to a chapel.

The Queens Villa, called Tenha Yuvah or Solitary Nest, is built in the traditional Revival period style and is surrounded by Moorish-styled patios. A nymphaeum was a particular favorite area of the royal.

Swiss horticulturists designed the gardens using the natural terrain to create a garden with different landscapes, each personally named by the Queen, for example “Gethsemane Garden” and “God’s Garden”. Today the gardens are managed by the Horticultural Society and contains over 2000 plant species.

It was also the place where the Empire’s treasure rooms were located. This magnificent fortress was captured, its treasures looted, and what was left destroyed during the Ottoman invasion of 1393.

The ruins visible today date from the 10th century and is the fort where the Peace Treaty of Lovech was signed with the Byzantine Empire, marking the beginning of the Second Bulgarian Empire.

This stronghold kept the Ottoman invaders at bay, and it was one of the last fortresses conquered by the Turks in 1446. By this time, it had become an important trade centre in Bulgaria and was a great loss to the empire.

This enchanting Fairytale castle was featured in the film “In Love with the Wind” and is the childhood dream of architect and builder Georgi Kostadinov Tumpalov.  In 1996, the eccentric millionaire took a spade and drew a cross on the site where the castle stands today. Tumpalov, his family, and local workers took 20 years to build this dream castle.

Ravadinovo is built with 20,000 tons of marble hewn from the Strandzha Mountains. The castle, chapel, towers, fountains, artificial lake, and walls are all built with this magnificent marble that contains traces of micro-diamonds which makes the stones change color in different light.

In the morning sun, the enchanting castle is imbued with shades of pink; in full daylight the castle is bright white; and during full moon, it shimmers and glows.

The armies of Simeon the Great conquered the well-located fortress but it was returned to Byzantium in return for recognition of Simeon’s Imperial title by the Bulgarian rulers. Ustra fortress frequently changed hands between the two empires from the 12th to the 14th century and was abandoned early in the 15th century.

The walls built of stone blocks are well preserved, 33 feet at the base and in some areas 370 foot high. Today you can see one semicircular tower and two rectangular towers that are 3 storys high. Climb the still intact stairways to view the spectacular region from the top.

Residential buildings and two churches were excavated in the inner city, showing frescoes from the Medieval period.

Fortified by the renegade brothers of Tsar Smilets of Bulgaria, Vovosil and Radoslav, who ruled this quasi-independent region for a short period of time. The original fortified complex covered an area of around 86,000 sq feet, with the inner town the size of 54,000 sq feet. Two towers with a 328-feet-long curtain wall still stand today.

Asen Fortress is named after Tsar Ivan Asen II, the reigning Tsar at the time of the reconstruction in 1230. This is confirmed by an eight-line inscription on one of the outer walls. The fortress is located on a rocky outcrop above the Asenitsa River. From its vantage point 915 feet above the river, the stronghold could defend against Roman invaders.

Archaeological findings date from the Thracian period through Ancient Roman, early Byzantine, and Crusades, until being finally conquered and destroyed by the invading Ottomans. Excavations have uncovered a feudal castle with 30 rooms and notably three water repositories for clean mountain water. The Ottomans left the beautiful brick church “The Holy Mother of God” which is in regular use today by the Bulgarian Orthodox church. On the chapel, walls are beautifully restored murals dating from the 14th century.
