El Retiro, Historic estate in Florida, United States.

El Retiro is a 12,900-square-foot, 20-room Mediterranean-style villa at 1151 Tower Boulevard in Lake Wales, Florida, designed by Charles R. Wait and completed in 1929–1930. It has a barrel-tile roof, thick walls, carved doors, dark wood interiors, wrought-iron details and three large porches. The surrounding formal gardens were designed by William Lyman Phillips of the Olmsted Brothers firm.

Charles Austin Buck, a Bethlehem Steel executive, had landscape architect William Lyman Phillips of the Olmsted Brothers draw up the grounds in 1929, then commissioned architect Charles Wait to design the Mediterranean-style villa, finished in 1930. Buck kept it until 1945. Nellie Lee Holt Bok bought it in 1970, renamed it Pinewood Estate, and Rudy Favretti later restored the gardens. It joined the National Register on December 12, 1985.

Buck, a Bethlehem Steel executive who admired Spanish-Italian living, named the winter home El Retiro, Spanish for retreat. The name Pinewood Estate, adopted after Nellie Lee Holt Bok bought it in 1970, refers to the longleaf pines growing on the grounds. Volunteer guides lead groups of up to twelve through rooms still furnished as in Buck's day.

The estate is accessible to visitors during scheduled tours that include both interior spaces and the surrounding gardens. It is wise to check opening hours in advance and wear appropriate clothing for Florida's subtropical weather conditions.

Buck imported the antique furniture from France, Italy and Spain, and most of the furnishings date from his years in the house. Tours of up to twelve people are led by volunteer guides through the rooms. The gardens hold a cross avenue of lemon trees and a walled Victorian garden entered through a moon gate.
