Poyos

Poyos — more fully, Santa María de Poyos — is a former village in the municipality of Sacedón, in the province of Guadalajara, in the Spanish region of Castilla-La Mancha. There are no streets left to walk here: the settlement lies beneath the waters of the Buendía reservoir, and visitors come not to explore a townscape but to trace the story of one of several Alcarria villages sacrificed to the large hydraulic projects of 20th-century Spain.

Why is there no village left to see?

Poyos stood in the Guadiela river valley, where the rolling countryside of La Alcarria meets the waterway that feeds into the Tagus. In 1956, once the dam across the Guadiela was completed, the Buendía reservoir began to fill and the village disappeared under its waters. It was one of many settlements in this part of Spain displaced by the construction of large reservoirs on the Tagus and its tributaries — the neighbouring Entrepeñas reservoir, closer to Sacedón itself, was part of the same wave of projects. What remained of Poyos's municipal district was folded into Sacedón in 1967.

What was life like before the flood?

Around 110 families lived in Poyos before the waters rose, most of them working the land. Vineyards were a mainstay, and wine was stored in cellars cut into the rock — some of these still resurface above the waterline during severe droughts, when the reservoir's level drops sharply. River-powered mills ground grain for the surrounding farms, and daily life followed the rhythm of the agricultural calendar.

Where were the villagers resettled?

The families of Poyos were scattered across several parts of Spain. Fifty families were relocated to San Bernardo, in the municipality of Valbuena de Duero (Valladolid), and another fifty to Paredes de Melo, in the province of Cuenca. The remaining families were split between Guma, in the municipality of La Vid y Barrios (Burgos), and Cascón de la Nava, in the municipality of Villaumbrales (Palencia). In Paredes de Melo, the newcomers carried their parish traditions with them, including devotion to the patron saints of Poyos.

What can still be found at the site today?

Along the road that skirts the reservoir stands a small hermitage dedicated to San Andrés, patron of the vanished village. It is here that descendants of Poyos's former residents gather to keep its memory alive. In 2012, more than six hundred people with ties to the village took part in a large commemorative gathering: a procession to the hermitage, a display of old photographs, and the unveiling of a memorial plaque.

When is the best time to visit?

Every year, on the fourth Sunday of September, a romería (pilgrimage) is held nearby in honour of Nuestra Señora de la Soterránea, the patroness of Poyos — a living tradition still tied to the sunken village. In particularly dry years, when the Buendía reservoir's water level falls significantly, traces of the old settlement resurface, including the rock-cut wine cellars — a rare chance to glimpse fragments of the village as it once stood.
