How old is the shelter covering the Casa Grande?
The original shelter roof was constructed in 1903 of redwood timbers and corrugated iron and by the mid-1920s it had begun to deteriorate. Although Frederick Law Olmsted, Jr. designed a new roof in 1928, funding for the project was not appropriated until 1932. Construction of the new roof was completed on December 12, 1932. Its final cost was $27,724.12, which included $4,000 for engineering and design costs.
