"Harwelden" is Welsh for "place from which the Harwell's came. This name, given to the house in 1967 by the Arts and Humanities Council, is very appropriate since Mr. Harwell's family came to the United States from Wales.

The home was completed in 1926 and has 30 rooms, four levels, and seven fireplaces. The main floor rooms and stairway are decorated with hand carved wood designs, all a part of a motif which comes from a coat of arms. The coat of arms consists of two shields, a lion and a flower.

The outside of Harwelden boasts carved Indiana limestone, a slate roof and limestone gargoyles, not to mention a gold fish pond and carriage house where the servants lived. Years ago the gold fish pond served as a pool for the Harwell's daughter, Margo.

Mary and Earl Harwell lived quietly but generously. They were very supportive of the University of Tulsa and Mr. Harwell was key in the founding of the Tulsa Boys Home. Mrs.

Harwell continued the family's charitable contributions and, upon her death in 1967, bequeathed Harwelden to the Arts and Humanities Council to provide a base for Tulsa's arts organizations.

In 1978 Harwelden was one of five Tulsa landmarks to be placed on the National Register of Historic Places. In 1983 Harwelden again made history by being part of an area placed on the National Register of Historic Places, the Mapleridge District.

The Arts and Humanities Council has maintained Harwelden for public use, and it serves today as a location for many of the Council's programs in arts education, literary arts, humanities and arts advocacy as well as a site for private functions.
