Leave Lugo on N 640, going south, and in 4km/2.5mi turn right into the road to Friol, from which a narrow road on the left is signposted to Bóveda. This passes through a verdant region of woodland and meadows, with areas of pastureland and small fields enclosed by granite walls. The tiny village of Bóveda is worth seeing for its own sake, with its low slated granite houses enclosed by walls and its hórreos (maize stores) - the very picture of a typical old Galician village.
Bóveda's particular attraction, however, is the little church of Santa Eulalia de Bóveda, in the basement of a house on the left at the entrance to the village, which has been declared a national monument. The church is believed to have originally been a Roman nymphaeum (shrine housing a sacred spring) which was converted to Christian use. In the center of this underground chamber, which was of pre-Christian origin, is the basin of the spring, and on the walls are paintings of birds, animals and Christian symbols.
