Porta Garibaldi closes the western end of Via Garibaldi about a kilometre from the cathedral. It is a triumphal arch in alternating bands of black lava and white limestone — Catania's signature material combination — built in 1768 to mark the marriage of Ferdinand IV of Naples to Maria Carolina of Austria.
The gate is one of the most photographed monuments in Catania, especially in evening light when the contrast between the stones is at its sharpest. A small park has been laid out around it.
