What is "allgates"

The Allgates is located in Haverford, Delaware County, Pennsylvania. The large estate contained 19 buildings. The largest of them is the Mansion House, designed by Wilson Eyre, and completed in 1912. The Frog Tavern was built in 1731, and the Federal School was built in 1797. The complex of buildings was added to the National Register of Historic Places on May 15, 1979, and the Federal School was listed separately in 1971. The estate was built for financier Horatio Gates Lloyd, who was simultaneously a partner in Drexel and Co. and J.P. Morgan and Co., as well as President of the Commercial Trust Co. of Philadelphia.

Since Allgates listing on the NRHP, the estate has been developed with several new large residences. Both the Mansion House and the Federal School remain, however.
