The main mode of communication of the parish is the CD-2 road, which links Aces Sandiche (Murias Parish) and Ferreras (parish of San Roman). It also has a station connecting to railway line built by the General Society of Asturian Basque Railways, which is now operated by LVEF and integrated into the local network of Asturias as line F-7, which communicates with Aces and San Esteban de Pravia Oviedo.
The parish is considered one of the areas of Asturias with a large number of granaries, most of them of great antiquity with numerous engravings on the doors. Prieto Bances refers to the weavers who used to be in Aces.
The parish church, dedicated to the Apostle Santiago, belonged to Queen Velasquita who in 1006 donated it to Bishop Ponce de Oviedo. The present building is nineteenth century but was rebuilt after the Spanish Civil War.
