Castelldefels

Castelldefels is a coastal town stretching between the Garraf Massif and the sea with more than 6 kilometers of sandy beaches and wild natural spaces. The landscape combines open beach areas with quieter coves and woodland paths behind the shoreline.

An 11th-century castle formed the original settlement as a defense against pirates attacking the coast. Additional watchtowers were built in the 17th century to strengthen this protective role along the shoreline.

The place takes its name from a medieval fortress whose name means 'castle of faithfulness,' and this history continues to shape how locals and visitors understand the town. The castle remains a symbolic landmark that connects people to centuries of coastal heritage.

The town is about 20 kilometers from Barcelona and connects easily through regular train service and the C-31 coastal highway. Summer months bring crowds to the beaches, while spring and autumn offer quieter conditions for walking or relaxing by the water.

The Castelldefels Astronomical Observatory offers specialized equipment for studying stars and planets and hosts regular stargazing sessions throughout the year. It is an unexpected addition to a beach destination that gives visitors a way to explore the night sky.
