This morning, the coastal fog has engulfed Gavà, in the Baix Llobregat, and the castle of Eramprunyà, next to the Garraf massif, was totally lost among this ghostly meteorological phenomenon.

Fog is a meteorological phenomenon that consists of the suspension of very small water droplets in the atmosphere or of moist hygroscopic particles, which reduce horizontal visibility to a distance of one kilometer or more. If the meteorological phenomenon gives a vision of 1 km or less, it is considered fog; and if it allows you to see more than 1 km, the phenomenon is fog.

In medieval times, the castle of Eramprunyà came to control the current territories of Gavà, Begues, Castelldefels, Sant Climent de Llobregat, Viladecans and part of Sant Boi de Llobregat.

Built as part of the defensive system of the border between Al-Andalus and the Carolingian Empire, it was owned by the counts of Barcelona.

Today, the remains of the castle can be seen on top of a mountain between cliffs with magnificent views of the Llobregat Delta and part of Garraf.
