Born in 1985, the Del Mar Historical Society houses memorabilia, photos and exhibits. Check out the Alvarado House, the first lot built in Del Mar, at the San Diego County Fairgrounds. During the Fair, the house is open to the public and docents to tell the history of Del Mar. Once a famous church for movie stars, Del Mar Library is a historic landmark worth a visit. Designed by local artists in 2002, a mixed-media mosaic wall frames the historic building.
The wall blends memorabilia and treasures from Del Mar's history and features terracotta birds and wildlife. In Encinitas, the San Dieguito Heritage Museum interprets the history of the San Dieguito River area, including the communities of Del Mar and Solana Beach.
