The tower's original clock mechanism was commissioned in 1729 by the locksmith František Gränzl.
The base of the tower is constructed with thick stone masonry, transitioning to a narrower, lighter upper structure typical of Renaissance defensive architecture.
An iron sundial remains attached to the exterior wall, though it is no longer the primary timekeeping source.
The tower was part of a larger defensive network that included the city's extensive medieval fortification walls.
A complex series of gears and weights for the clock occupies the interior space, accessible to visitors during the climb.
The City Tower in Trnava, Slovakia, is a Renaissance-style watchtower constructed in 1574 to serve as a defensive lookout and fire observation point. Standing 57 meters tall, the tower is built on a square ground plan and features a prominent iron-wrought sundial and a clock mechanism dating back to the 18th century. It is located at the heart of the city's historical square, providing an elevated vantage point over Trnava’s preserved urban core. The structure has undergone several restorations, most recently reinforcing its role as an accessible landmark. Visitors can ascend to the gallery via a restored staircase to view the mechanical clock interior. It represents one of the most recognizable examples of Renaissance architecture in the region.

Wear comfortable, flat shoes as the interior staircase consists of multiple flights of historic, uneven steps.
Visit on a clear day to identify the surrounding Malé Karpaty mountain range from the observation gallery.
Look for the original stone coat-of-arms of Trnava embedded in the masonry.
Do not attempt the climb if you have mobility issues or a fear of confined, winding staircases.
The interior observation level may close briefly during severe weather or for routine clock maintenance.
