The Collins-Wellington Estate, an architectural gem in San Diego, presents a Spanish-Revival Castle built in 1928 by H. A. Collins. Nestled atop an 8-acre private hill, this estate offers a rare combination of seclusion, grandeur, and historical significance, listed on the Historic Register and benefiting from property tax savings under the Mills Act. This 5,766 square foot mansion features intricate old-world craftsmanship, including high beam ceilings, inlaid onyx floors, hand-painted ceiling designs, and oak flooring with peg and bowtie detailing. The design boasts genuine Spanish Castle motifs, with repeating arches and wrought iron details that harmonize throughout the estate. The residence includes four bedrooms, each with en-suite baths, and ample space for sitting areas or home offices. A double foyer with stone castle walls and a gold-gilded wrought iron staircase leads to an upstairs loft. The grand 35 x 25-foot ballroom/living room, with its 18-foot high cathedral ceiling and balcony, once hosted live musicians for dances below. A spacious dining room and an updated kitchen with a granite island enable grand-scale entertaining. The sunny breakfast nook sits below the castle's tower, and a massive 10-car garage offers extensive storage and parking. Outside, the expansive grounds provide ample space for relaxation and entertainment, including a sheltered courtyard, with potential for additional structures such as a pool or ADU. The estate commands stunning panoramic views of downtown San Diego, the harbors, and the Pacific. The Collins-Wellington Estate is more than a home; it is an unparalleled living experience and an architectural work of art. This once-in-a-lifetime opportunity allows one to own a piece of history and enjoy a tranquil retreat while remaining close to all San Diego has to offer.
