The Caves of Drach (Catalan pronunciation: [kɔvəz ðəɫ ˈdɾak], modern Catalan spelling: Coves del Drac, Spanish: Cuevas del Drach, English: "Caves of Drach", lit. "Dragon caves") are four great caves that are located in the island of Majorca, Balearic Islands, Spain.[1] They are in the municipality of Manacor, near the locality of Porto Cristo. They were first mentioned in a letter 1338.[citation needed] The caves extend to a depth of 25 m and reach approximately 4 km in length.[1] The four caves, called Black Cave, White Cave, Cave of Luis Salvador, and Cave of the French, are connected to each other.
