Perched on the steep hillsides of the Pacific Palisades overlooking the Pacific Ocean, Castellammare is a picturesque neighborhood reminiscent of the Italian Riviera. Located at the junction of Sunset Boulevard and Pacific Coast Highway, this tranquil seaside enclave offers stunning coastal vistas and a serene atmosphere. Despite its peaceful setting, Castellammare is just minutes away from Palisades Village, downtown Santa Monica, and is bordered on the west by the iconic Getty Villa.

The lower reaches of Castellammare feature narrow, winding streets that add charm and privacy to the community. As the hillside ascends to a gently sloping upper mesa, homesites become more accommodating to larger properties, including those with swimming pools. While most homes are modest to moderate in size, the neighborhood has seen the development of larger, second generation residences. These newer builds, some with up to 8 bedrooms and over 8,000 square feet of living space, stand out and often command premium prices well above the community average.

The Castellammare Mesa Homeowners Association (CMHOA) serves as the neighborhood's representative body. Participation in the HOA is optional, with voluntary annual dues. The association actively maintains an architectural review committee to preserve the area's charm and organizes social events to foster a sense of community. Residents also benefit from a quarterly newsletter that highlights local updates and activities.

In addition to its single-family residences, Castellammare is home to a selection of high-end condominium developments that elevate the neighborhood's appeal. Notable projects include One Coast, Rockwell at PCH, and Ocean Woods Terrace, which offer luxury living with ocean views and modern amenities.
