The Collins-Wellington Estate | Spanish-Revival Masterpiece on 8 Private Acres – Mills Act Designated Step into timeless grandeur at the Collins-Wellington Estate, a one-of-a-kind Spanish-Revival castle nestled atop 8 secluded acres in the heart of San Diego. This historic 1928 architectural marvel was envisioned by H.A. Collins and later cherished by the prestigious Wellington family—famed for hosting soirées attended by Southern California’s elite. A gated, tree-lined drive welcomes you with a quarter-mile of privacy and anticipation, leading to a majestic 5,766 sq ft residence rich in heritage and soul. Listed on the Historic Register and benefitting from significant tax savings under the Mills Act, this estate is truly a legacy property. Inside, every corner tells a story—original peg-and-bowtie curly oak floors, hand-painted ceiling designs, inlaid onyx flooring, and soaring 18-foot cathedral ceilings blend seamlessly with the intricate wrought iron and arched motifs that define authentic Spanish architecture. Enter through a regal double-height stone foyer with gilded detailing and a stunning wrought-iron staircase lined with hand-painted Spanish tiles. The 35’ x 25’ grand ballroom—once alive with the sounds of live musicians serenading from the balcony above—is a crown
