Waveny Park in New Canaan, Connecticut was originally a grand summer estate owned by Thomas Wells Hall from 1894 to 1904. The Carriage Barn and Powerhouse were built during this period. In 1904, Lewis Henry Lapham, a co-founder of the Texaco Oil Company, bought the property as a summer estate from Hall, renamed it Waveny, and expanded it from 280 acres to 450 acres.  Lapham tore down Hall's house and had a new one built in 1912 by the renowned architect William B. Tubby. The landscape design for the property was by Frederick Law Olmsted, Jr.

In 1967, Ruth Lapham Lloyd, who inherited the estate from her father and lived there full-time, entrusted the entire estate, including Waveny House, to the Town of New Canaan for $1,500,000. Today, the park consists of 300 acres (1.2 km2) of fields, ponds, and trails.
