Among the few architectural masterpieces of the 16th century that have survived to this day is the Gremyachaya Tower in Pskov, one of the oldest defensive structures in Russia. It was built in 1525 on the steep bank of the Pskova River on Gremyachaya Hill. The tower has a massive base with a diameter of 15 meters. Once, its height was 15-20 meters, but exact data is hard to establish since the wooden dome has not survived.

The tower was divided into six tiers with platforms, each housing cannons ready to repel an attack. Despite its narrow appearance, a whole garrison of soldiers could be accommodated inside with proper distribution.

The structure had a secret passage for supplying defenders with water and provisions. The Gremyachaya Tower was protected on two sides by massive fortress walls. Since they crossed the river, special water gates with grates were provided. In peacetime, they remained open, but were lowered in times of threat.

Interestingly, due to the unusual architectural forms characteristic of Central Europe, some researchers believe that a Russified Italian named Ivan Fryazin may have been involved in its construction.

Many myths and legends are associated with the Gremyachaya Tower. One of them tells of a cursed daughter of a local prince who sleeps in the dungeons. For her disobedience, her mother cursed her, and only a brave young man who reads the Psalter by her bedside can lift the spell.

Another legend recounts a prince who preferred to die rather than surrender in a battle against the Swedes. Upon learning this, his army launched an attack on the enemy. In the bloody battle, the odds were uneven, but suddenly the image of the fallen prince appeared on the wall of the Gremyachaya Tower. The frightened Swedes retreated and were defeated. Today, the Gremyachaya Tower is a popular destination for tourists.
