Biguglia is located at an altitude of 116 metres and is part of the ancient parish of Orto, of which it was the most important village. The river of Bevinco – whose the stream of Petrelle and the stream of Ficabruna are the major tributaries – ends its course in the pond of Biguglia, which is the largest pond in Corsica. Here you can find more than 120 species of birds, such as the greater flamingo, the great cormorant, the common kingfisher and the moustached warbler, and several amphibians and reptiles that are at risk of extinction, such as the Tyrrhenian painted frog, the Hermann's tortoise and the European pond turtle.
Biguglia benefits from a Mediterranean climate with moderate temperature variations thanks to the beneficial influence of the sea and of its proximity with midlle mountains.
This village is part of a second-generation natural area of ecological, faunal and floristic interest: Étang, zone humide et cordon littoral de Biguglia. The village is also part of two Natura 2000 sites: Habitats, faune, flore – Étang de Biguglia and Oiseaux – Étang de Biguglia.
Under the authority of Vincentello d'Istria (1380-1434), this village was the capital of Corsica for a few years. Today you can still run into some ancient vestiges of its prestigious past, such as the old Roman road and the ruins of an ancient castle.
Art lovers can visit the parish church of St Andrew (16th century), which is in excellent condition because the interior was restored in 1994 and the exterior in 2008. This church has three altars, the main one is dedicated to Saint Andrew. In Biguglia you can run into the ruins of several chapels, the most important of which was the chapel of St Andrew of Fabrica (13th century). This chapel is located at a fifty-minute walk from the village and overlooks the plain and the pond of Biguglia.
Biguglia is located at 11 km from Bastia, at 62 km from Corte and at 66 km from Aléria. This village is crossed by the T11 road.
