In 1875, the Raventós family sold the old farmhouse Plana Novella to Pere Domenèch i Grau, a resident of Cuba. The new owner included his possessions under the benefits of the colonial law, obtaining an exemption from consumption tax and other services for the families living there. The construction of the palace was completed on October 29, 1890. The owners only enjoyed it for six years because they went bankrupt due to the phylloxera outbreak in 1893. As a result, the estate was put up for public auction in 1896. Since then, the palace has had different owners who kept its doors closed until 1996 when a Buddhist community moved in, restoring the building and establishing a museum.

The Gavà Archaeological Museum, established in 1978, showcases the rich archaeological heritage of the Garraf region, featuring the Prehistoric Mines of Gavà and the cave of Sant Sadurní. With a focus on research, conservation, and heritage dissemination, the museum provides a fascinating journey through millions of years of landscape history.

Dating back to 957, the castle served as a vital stronghold controlling territories including Gavà, Begues, and Castelldefels. Its strategic significance in the defensive system between Al-Andalus and the Carolingian Empire made it a key political, economic, and military center. Despite facing destruction during the Catalan Civil War in 1469, it witnessed a succession of owners and was eventually acquired in the late 19th century by banker Manel Girona, a figure associated with the completion of Barcelona Cathedral's façade.

Campdàsens is the name of a hamlet and scattered settlement in a valley within the Garraf Massif, located in the municipality of Sitges (Garraf). It features a square defensive tower, documented in 1097 and modified in the 16th century, a 19th-century hermitage, and several farmhouses.

Jafre, an ancient hamlet atop a 189-meter hill, now stands abandoned. The remnants include the Baron of Jafra's residence, the farmhouse, and the Church of Santa Maria de Jafre, along with its rectory, dating back to the early 14th century. Documented since 1139, Jafre received significant attention in the 17th century when the Barons sought to rejuvenate the village, appointing a mayor in 1683 and restoring the church. In 1819, Jafre became part of Olivella due to parish ties. Traditionally focused on firewood and pastures, vine cultivation thrived until the phylloxera epidemic (1879-1880) led to gradual abandonment. As of 1960, Jafre was left with 19 inhabitants.

La Pleta is a modernist building located in the Garraf Natural Park, within the municipality of Sitges. Originally constructed as cattle pens for the Guell family, it was built in 1894 and is attributed to Francesc Berenguer i Mestres, the same architect responsible for the Güell Cellar in the nearby town of Garraf. The building serves as the headquarters of the Garraf Park Office (see #understand).

La Morella is the highest peak in the Garraf Massif, reaching an elevation of 593.6 meters. The surrounding area features several sinkholes. A long-distance trail, GR 92 Sender del Mediterrani, passes through this mountain summit in its 21st stage from Bruguers to Garraf.[ It coincides with a local short-distance trail (SL-C 99)[ covering 6.1 km, extending from the Environmental Activities Center of Cal Ganxo (Castelldefels) to La Morella.
