Gaslamp Museum at the Davis-Horton House

An 1850 house at 410 Island Avenue, pre-fabricated in the saltbox style and shipped from the United States East Coast, which the encyclopedia describes as the oldest structure in the New Town San Diego area that William Heath Davis helped establish. The same article records that this particular building was not Davis's own house but one of the same style and age. The encyclopedia describes the house as open to the public as a museum, operated as the Gaslamp Museum at the Davis-Horton House, and the museum's own site gives hours of 10 a.m. to 4 p.m. from Thursday to Saturday, with last entry at 3:30 p.m., and states that it serves as headquarters for the Gaslamp Quarter Historical Foundation. No independent source confirming that it is operating today could be reached — the Gaslamp Quarter Association's own business directory carries no listing for it under any of its names — and the date it opened as a museum is not established either.
