The kilometer marker under Michael’s Gate, also known as the Zero Kilometer, shows the distances from Bratislava to major world capitals as well as to the North and South Poles. It also displays the partner cities of the Slovak capital.

The brass marker is embedded in the city pavement directly beneath Michael’s Gate. Together with the gate and the entire Michael’s Gate, it is one of the most popular attractions in the Old Town, partly due to its excellent accessibility. The original marker, created in 1997, was designed by Viktor Hulík.
The easiest way to reach the Bratislava kilometer marker is by public transport, with the closest stop being Kapucínska Street, from which it is a short walk. Cars are not permitted, but bicycles are allowed.
The kilometer marker makes an interesting destination for a walk through the Old Town, especially for families with children. Its visit pairs well with a trip to the Weapons Museum in Michael’s Gate. Climbing the tower’s floors rewards visitors with expansive views of much of the Old Town and excellent photo opportunities.
Among the interesting facts displayed on the marker is that the farthest city from this point is Sydney, Australia, at 16,000 km, while the closest is Vienna, at 60 km. In 2013, the marker was reconstructed by sculptor Ľubomír Mikle, assisted by the original author, following vandalism and partial theft.
A curious detail from this restoration is a minor error showing identical distances from the North and South Poles. The renewed marker was crafted over three days of nearly continuous work from a 105 kg plate originally from Germany.
