Beatles and music icon John Lennon and his wife Yoko Ono purchased the oceanfront estate on Palm Beach’s billionaire’s row known as El Solano for $725,000 in 1980. That same estate is now back on the market for $47.5 million. El Solano was built in 1925 by iconic South Florida architect Addison Mizner before he sold it to Harold K. Vanderbilt.
