Firstly, there are outstanding megalithic remains such as Pico Las Nieves; Roman settlements in the district of Reinosa, with the ruins of Julióbriga, Camesa-Rebolledo and pre-Roman art in the temple of Santa María de Lebeña; as well as the valuable rock-hewn churches of Campóo and Valderredible.
Secondly, multiple Romanesque churches have been preserved, such as the Colegiata de Santillana del Mar, the Colegiata de Santa Cruz de Castañeda, the Colegiata de San Pedro de Cervatos and the Colegiata de San Martín de Elines, alongside a considerable number of instances of this style in Valderredible and, to a lesser extent, in the basin of the river Besaya and in Liébana.
The church of Santa María de la Asunción in Castro Urdiales is the most renowned Gothic building in Cantabria. Numerous palaces and mansions belong to the period between the 16th and 17th centuries, from the Renaissance to the Baroque. Some preeminent historic ensembles are in Liérganes, Alceda, Cartes, Potes and especially Santillana del Mar, as well as several individual palaces like Los Acebedo in Hoznayo, Elsedo in Pámanes and Soñanes in Villacarriedo.
As to 19th-century architecture, the town of Comillas boasts the Palace of Sobrellano and the Pontifical University, along with Gaudí’s El Capricho, the Cemetery and Llimona’s Angel as instances of Catalan neo-Gothic and Modernism.
