Sveta Katarina, Islet and coastline near Rovinj, Croatia

Sveta Katarina is an uninhabited islet at the entrance to Rovinj harbour, 260 m from the mainland. It is 640 m long and 340 m wide, with an area of 0.124 km² and a coastline of 1,825 m. The eastern side has rocky beaches, while the northern part ends in vertical cliffs called the Golden, Silver and Bronze rocks.

In the 19th century, the island was bought by Archduke Karl Stephen, then later by Count Ignaz Milewski, who had a summer house built there. Milewski also brought in soil to cover the bare rock and created a planted park, which shaped the island's green character that remains today.

The island's name comes from Saint Catherine, and its most visible feature is the group of three cliffs on the north side, called the Golden, Silver and Bronze cliffs. The eastern side has rocky beaches that visitors use for swimming and sunbathing. The island is reached by a boat that runs every hour from Rovinj.

Boats run hourly from Rovinj to the islet's landing, and the crossing takes only a few minutes. The island is elongated, pinched in the middle and oriented west-east, with the landing on the side facing Rovinj. Paths are rocky throughout, so sturdy footwear helps.

The green park covering the island exists only because Count Milewski had soil brought in from elsewhere in the 19th century, as the ground was originally bare rock. Without that effort, the island would look much more barren than it does today.
