The Prince's Tower, located in the southwestern part of the Novgorod Detinets, is a quadrangular blind tower. Its plan is square, measuring 9 by 9.8 meters. The height of the tower with battlements reaches 18.5 meters, and the thickness of the walls at the first level is 2 meters. The tower is topped with a ten-meter tent. Originally, it had six tiers, with the first and third tiers supported by brick vaults, which have now been dismantled. Previously, the tower had exits to the walls, which are now bricked up.

Over time, the tower has been referred to by different names: in 1626 it was mentioned as "behind the Boyar's courtyard" or "in the Tsar's courtyard," that is, in the Voivodeship courtyard. In the 1660s and 1670s, it was called "Vlasyevskaya," and in 1694, named after the church of Vlasiy on Volosovaya Street, to which the tower's facade faces. It was built between 1484 and 1499, likely on the site of an older structure. The modern name of the tower appeared in literature in the early 20th century.

The tower underwent changes in the 16th century and during the construction of the Voivodeship courtyard in the late 17th century, when a two-story building was added to it for the needs of the Voivodeship courtyard. The first floor of the tower housed a cellar, while the second floor contained a drying room and food storage. In 1784, it was adapted for the archive of the Treasury Chamber. During archaeological excavations conducted by N.K. Rerikh in 1910, the lower part of this annex was discovered.

During the Great Patriotic War, the Prince's Tower was separated from the walls but withstood the test. In 1957, it was studied by A.V. Vorobyov and M.Kh. Aleshkovsky. On April 30, 1991, a section of the wall near the Spasskaya Tower collapsed, and on the night of May 3-4, another part of the wall between the Spasskaya and Prince's Towers fell. In 1994 and 1996, a new wall was built to replace the collapsed fragment between these towers.
