Pico Pienzu, Mountain summit in Sierra del Sueve, Spain.

Pico Pienzu, at 1161 m, is the highest point of the Sueve coastal range in Asturias. Its summit is crowned by a sixteen-metre iron cross, reached by a steep path from the Mergullines meadow, which has a fountain. Below the summit lie pine woods and the Bustaco meadow, where Asturcón horses often graze.

The summit's iron cross, sixteen metres tall, was raised in 1954 with help from many Sueve residents. It replaced a seven-metre wooden cross put up in 1916, which weathered away and was followed by a larger wooden one, also destroyed by a storm. The crosses were donated by the Victorero brothers of Lastres; a storm bent the iron cross, and the Asturian firm Industrias Alqui repaired it in 1973, again paid for by the Victorero brothers.

The summit cross is a donation from the Victorero brothers of Lastres: a seven-metre wooden cross was put up in 1916, replaced after storm damage, and the current sixteen-metre iron cross was raised in 1954 with help from Sueve residents. It bent in a storm and was repaired in 1973 by the Asturian firm Industrias Alqui, again funded by the Victorero brothers.

The usual route starts at the Mirador del Fito, where a marked path on the opposite side climbs through pine woods to the majada del Bustaco, a large pasture with a fountain where asturcones often graze. A steep track continues to the majada de Mergullines, with another fountain, and from there the summit cross is easily reached. A recently signposted alternative leaves from Cofiño, in Parres, with an information panel at the village entrance; it takes about two and a half hours up and just under two hours down, sharing the final stretch with the Fito route.

The 16-metre iron cross on the summit was placed in 1954 with help from many Sueve residents; an earlier 7-metre wooden cross from 1916 was destroyed by storms. The crosses were donated by the Victorero brothers of Lastres, and Asturian firm Industrias Alqui repaired the iron one in 1973 after gales bent it.
