About Sant Pere de Martir to Valvidrera Reservoir

This is a 7km easy walking route in Parc collserola via Ariel bombardment gun emplacements from the civil war then to Sant Pere de Martir telecoms tower and along the ridge with views of Barcelona. Once at Vallvidrera village the route is via forest paths down to the Vallvidrera reservoir and terminating at Valvidrera Baixador station.

Between 1834 and 1856 there was an optical telegraph tower at the summit of Sant Pere de Martir which was used to communicate with Ordal, Montjuic castle, Martorell, Moulins de Rei etc. A hermitage and small fortress were demolished to build the modern Telecoms tower.

After Sant Pere de Martir sumit the route follows along the top of the ridge with views of Barcelona and Parc Collserola along the way, passing via a shrine

Vallvidrera Reservior was built from 1850 to 1860 by architect Elias Rogent to garantee a supply of water to the Sarria district of Barcelona. The dam measures 50 metres wide by 3 metres thick and 15 metres high. The reservoir can hold up to 18 thousand square metres of water. The base is hollow and contains a tunnel that is used for draining the cement and inspection of the wall. The reservoir fell into disuse in the 1960s due to it filling up with sediment. Today the reservoir and dam is being preserved as part of the Parc natural Collserola.

Grott tunnel, built 1855, to take stone quarried in Colserolla to la Sarria district of Barcelona via railway. The tunnel also carried 400.000 litres of water daily from the reservoir into the Sarria district of Barcelona. The tunnel is approximately 1Km long and exits the mountain near the FGC funicular de Valvidrera inferior station. After the construction of the FGC line this tunnel was no longer needed and fell into disuse.

The pink guard house is now a small museum about the reservoir and has very limited opening hours.
