The Rance Tidal Power Station was one of the first hydroelectric power stations in the world when it first opened in 1966. Today it is the world's second biggest tidal power station. There are boat tours up the river during high season, during which you can enjoy a lovely view of the bay.

The Orihuela Archaeology Museum has its origins in the former Santo Domingo Museum of Antiquities, established in 1902 by Jesuit priest Julio Furgús, who donated numerous pieces. Created by the Orihuela Town Council, the museum has been housed in various locations, including the Palacio de Teodomiro, the Municipal Hospital, the Rubalcaba Palace, and since 1997, its current location at the Church of San Juan de Dios, which was built in the mid-18th century. The museum's collection features artefacts that span a broad range of periods, from the Paleolithic era to the early 19th century. The majority of the items were excavated or discovered in the town and its surrounding areas, often through the museum's own investigations. The same building also houses the Exhibition Hall, formerly the men's ward of the hospital. This spacious, rectangular room with barrel-vaulted ceilings hosts temporary exhibitions and various cultural events.

Constructed on the site of a former mosque from the Islamic city, this church dates back to between 1402 and 1417, according to the oldest documented evidence. Featuring a single nave design and side chapels nestled between buttresses, the original Gothic structure has undergone significant modifications due to restorations and extensions carried out between the 16th and 18th centuries. Notable elements within the church include a Renaissance presbyter, shaped like a triumphal arch, and the chapel dedicated to the Holy Family (1765-1766), which showcases the artistic influence of sculptor Francisco Salzillo. The main entrance of the church, adorned with the shield of the Catholic Monarchs at its peak, is in the Isabelline Gothic style. In contrast, the adjoining communion chapel exhibits a more Baroque aesthetic, featuring an entrance constructed between 1726 and 1735.

Carolina Rediviva was erected between 1817 and 1841 and is home to Sweden's oldest university library, founded in 1620. Originally three stories high with two mezzanines, the building now spans 12 stories and has about 5 million books and 3,500 shelf meters of handwritten documents. When you walk through the entrance of the library, you'll come to the exhibition room, where you can view the famous Silver Bible from the 6th century, musical notations made by Mozart himself, medieval manuscripts, and Olaus Magnus' Carta Marina, printed in 1539.
