Old Mission Dam

While San Diego is a young city in terms of history, it has a number of hidden historic gems. Many of these locations are clustered near the current city center (such as the Whaley House), but one of the spots, the Old Mission Dam, is located in the middle of San Diego's largest municipal park, Mission Trails. The Old Mission Dam is a historic structure for a number of reasons, but first and foremost, it is the oldest colonial engineering project on the Pacific Coast.
