Village
La Llacuna is the highest municipality of l'Anoia, in the serralada de l'Ancosa, whose Puig Castellar is the highest point in the comarca; it has 959 inhabitants and includes the centres of Rofes and Torrebusqueta. In its term are the Roca Roja cave paintings, discovered in 1982 and unique in Barcelona for preserving Levantine and schematic art, declared a UNESCO World Heritage Site in 1998. The village is mentioned in documents from 987, and in 1347 the barony of la Llacuna was formed. Its origin lies next to the church of Santa María, documented since 1020; the present parish church dates from 1734. High on a mountain, at 712 metres, remain the ruins of the castle of Vilademager, with its gateway and part of a tower, next to the church of Sant Pere de Màger.
Monument
Documented since 987 as the boundary of a donation by count Borrell II, built between the 10th-11th centuries; it passed from the comital house of Barcelona to the Cervelló family (1079), then to the Vilademàger family and around 1347 to the barony of la Llacuna. It retains a tower, sections of the enclosure, an entrance gate and walls, next to the Romanesque church of Sant Pere with Gothic elements from the 14th-15th centuries. A Bien de Interés Cultural (Spain's highest level of heritage protection) since 1988 (BIC RI-51-0005507).
Monument
Of the medieval wall that surrounded the village of la Llacuna (Anoia, Barcelona) barely anything survives: the enclosure, which formed a vila closa (walled town), had five access gates: d'en Bens, de la Font, d'en Badorc or de la Banya, del Vall and del Fort Micó. Only the Banya gate survives, in a deteriorated state, on Carrer de la Muralla. From the 15th century onwards residents gradually moved down to the valley as the enclosure's defensive function lost its meaning, giving rise to the village's present main square.
Monument
Els Castellots is the name of the ruins of a medieval fortified house located in the municipality of la Llacuna (Anoia), declared Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection). They are located near the les Vilates area and form part of a fortified mas, with the typical houses of the area, of stone and a double-pitched roof, comprising numerous buildings and a large entrance courtyard. It was formerly known as cal Martí del Bosc, to distinguish it from the mother house of mas Martí, and formed part of the quadra of Vilademàger, dependent for a time on the castle of Rocamora. Local tradition holds that this house was inhabited by saint Maria de Cervelló (Barcelona, 1230-1290), founder and first superior of the Mercedarian nuns.
Monument
The Castellot del Mas Martí, in the municipality of la Llacuna (Anoia), is a fortress of which medieval ruins survive, declared Bien Cultural de Interés Nacional (Catalonia's highest level of heritage protection). It is a not very large construction, more like a fortified house than a great castle — local tradition even recalls it as an old medieval hospital, and coins of the Catholic Monarchs have been found in it —. Its walls, of local stone and not very thick, preserve a round tower and a moat along the south side to make up for the terrain's lack of natural defence. Its history is uncertain, although in 1154 there is documentation of Bernat de Vilademàger, castellan of the castle of Mager, who owned among other properties the quadra of Vilademàger, probably linked to the castle of Bosc.
Monument
The church of Sant Pere de l'Arç, in the municipality of la Llacuna (Anoia, Barcelona), is an 11th-century Romanesque temple with a single nave, rectangular plan and semicircular apse. Given in 1038 to the canonry of Sant Vicenç de Cardona, it attained parish status in 1331 and was remodelled in the 18th century with Baroque additions. It preserves a Baroque altarpiece from 1642, the work of Josep Ribera and Gregori Ferrer, two other altarpieces from 1793 dedicated to Sant Sebastià and the Sant Crist, and an altarpiece of the Verge del Roser from the 16th century restored in 1793. It is now integrated into the village cemetery.
Nature
Puig Castellar is a mountain of 943 metres located in the municipality of la Llacuna, in the comarca of Anoia. It is the highest peak of the serra de la Llacuna, though not the highest in the comarca: it is surpassed by the summits of Montserrat, being the eighth highest in Anoia. On its summit there is a geodesic marker, and it appears, under the name Puig Castellar (serra d'Ancosa), on the list of the 100 cims of the Federació d'Entitats Excursionistes de Catalunya, a classic among hikers in the area.
Curiosity
Chalcolithic or Late Neolithic megalithic cist, dating from around 2500-2000 BC, in the municipality of la Llacuna.
