Depaldo Stairs, stone staircase in Taganrog, Russia

The Depaldo Stairs are a stone staircase 108 metres long and 6.5 metres wide, linking Grecheskaya Street with Portovaya Street and Pushkin Embankment. Designed by architect Franz Boffo, they were built in 1823 with 13 landings and 142 steps. The steps were originally paved with Sarmatian limestone; in 2006 they were replaced with granite.

The stairs were designed in 1823 by Swiss architect Francesco Boffo and funded by Greek merchant Gerasim Depaldo to solve a practical problem. They were built to help the growing population move more easily between residential areas and the harbor, becoming a key part of the city's infrastructure.

Since 2003 the city marks its annual City Day with a foot race up the stairs called "188 Steps". In summer the flight is washed weekly with fire hoses, and the lower squares once held fountains selling soft drinks and ice cream.

The stairs are easily reached on foot and offer a direct route between the city center and waterfront without crossing major roads. Sturdy footwear is recommended since the steps and surrounding areas can have varying conditions depending on weather.

The staircase's stepped widths were designed so that, seen from above, it appears the same width all the way down, while from below it seems to narrow. This optical effect, achieved by varying step widths, was later used for the Potemkin Stairs in Odesa.
