The Archaeological Museum is the institution that preserves, researches and exhibits the remains belonging to the historical past from the islands of Ibiza and Formentera. It is divided in two locations, both found in the city of Ibiza. Ibiza and Formentera's Archaeological Museum has a museographic content which spans three thousand years of Pytiusic history, from the first people who settled in the islands to the Catalan conquest in 1235. It is situated in an iconic spot inside the fortified city of Dalt Vila, in a place known as “Plaza de la Catedral” (Cathedral Square), which is the highest area of the city. In the surrounding area, we can find some historical buildings, such as the Castle, the Episcopal Palace, the House of the Curia, the old “Lonja” (a kind of market), which has currently become a viewpoint (from where you can enjoy incredible views of La Marina neighbourhood, the harbour and the modern new districts from the city), and Santa Maria church, which was constituted a Cathedral in 1785.
