The counties of Urgell and Cerdanya were part of a single territory in the 9th century but were divided among the heirs of Wilfred the Hairy on his death. In the 11th century the county of Cerdanya was annexed to the House of Barcelona. The Pimorent pass, the county’s most strategic point, was the source of many battles between the counts who wanted to make it theirs.
In 1659, part of Cerdanya (now Haute-Cerdagne), together with Roussillon, Conflent, Capcir and Vallespir, was ceded by Catalonia and Spain to the French crown under the Treaty of the Pyrenees. Three main roads cross the modern county: the N-260, from east to west; the N-152, at its eastern end, and the C-16, from north to south. These connect all the county's towns and villages, which are set in an indisputably diverse and beautiful landscape that ranges from alpine meadows to sub-Mediterranean forests.
Cerdanya is full of contrasts, from the plains watered by the Segre, the river that connects the county, to the high peaks surrounding them, many of them around 3,000 metres high.
There are no great monumental works in Cerdanya's Romanesque heritage, but the county's small churches are a picturesque feature of the natural landscape around them.
The ancient Monastery of Santa Maria de Talló, between Isòvol and Bellver de Cerdanya, and the parish church at Sant Pere d'Alp are among the most outstanding examples.
