Castell d'Estela

Castell d'Estela is the ruin of a medieval castle that once guarded the Ter river valley, perched on a ridge above the town of Amer in the La Selva region of Girona, Catalonia. Listed as a Cultural Asset of National Interest (Bé Cultural d'Interès Nacional), it rewards visitors with both a mountain hike and a thousand-year-old story.

Where exactly is the castle located?

The ruins sit atop the Serra de Saleres Velles ridge, the mountain chain separating the Ter river basin from the Brugent valley. This was no accidental choice of site: together with the Diable castle standing across the valley, Castell d'Estela controlled the point where the Ter river leaves the mountainous Guilleries region and flows out onto the plains of La Selva and Gironès. From this vantage point, the settlements of Amer, Cellera de Ter and Anglès could all be watched and protected.

What is the history behind it?

The fortification most likely dates from the 10th or 11th century, though the earliest written references — under the Latin name "castrum de Stella" — only appear in documents from 1080 and 1136. Seigneurial rights over the castle passed through the Montcada and Soler families, who became connected by marriage to the Roca-Salva family in the 14th century. For centuries the castle functioned as a watchtower and checkpoint over a key route linking the Guilleries mountains with the lowlands, making it a significant piece of the regional defensive network.

What survives on site today?

Time and natural disasters have not been kind to the structure. A powerful earthquake in 1428, which devastated large parts of Catalonia, badly damaged the castle, and its condition has deteriorated steadily since. Visitors today will find damaged and partially collapsed wall sections, terraces shaped by the steep terrain, and the foundations of a rectangular tower that once served as the main defensive element. The walls were built irregularly, from roughly hewn stones bonded with lime mortar and sand — a construction technique typical of Catalan strongholds of the period.

How do you get to Castell d'Estela?

The starting point is the town of Amer, from where a walking trail climbs the slope of the Serra de Saleres Velles. The route is a genuine mountain hike, so sturdy trekking shoes are recommended, especially after rain, when the path can turn slippery. The effort is rewarded not only with a close encounter with history, but also with sweeping views over the Ter valley and the surrounding Guilleries range.

When is the best time to visit?

Spring and autumn offer the best hiking conditions, with mild temperatures typical of the Girona region and excellent visibility from the ridge. In summer, an early start is worthwhile to avoid the heat on the largely unshaded ascent. In winter the trail can still be walked, but it's worth checking the forecast, as strong winds are common on the higher stretches.

Frequently asked questions

Is Castell d'Estela a fully intact castle? No. It is a ruin — surviving elements include sections of defensive walls, terraces shaped by the slope, and the foundations of a tower, but most of the structure was destroyed, largely by the 1428 earthquake.

Is there an entrance fee? The site is an open historical location reached on foot via a mountain trail, with no ticket booth or visitor infrastructure typical of museum-style castles.

How long does it take to reach from Amer? The climb is a genuine mountain walk — exact timing depends on fitness and the chosen route, but it's worth allowing at least an hour each way, with enough daylight left for the return.

How does Castell d'Estela relate to the nearby Diable castle? The two stood on opposite sides of the same valley and worked together to control the passage of the Ter river from the Guilleries into the plain — a pair of watchtowers guarding the same strategic corridor.
