I just returned from an architectural tour of Los Angeles sponsored by UNLV (University of Nevada/ Las Vegas). One of the highlights was the L.A. Historic Downtown (Pershing Square) walking tour given by docents from the L.A. Conservancy. This tour is held on Saturdays at 10 a.m. and lasts 2 1/2 hours. Our docent was extremely knowledgeable, well organized and very pleasant. The tour started in Pershing Square and then on to the Central Library. She explained that the city of L.A. was going to tear down the Central Library years ago, and that is when a group of citizens got together to protect it. The group eventually became the L.A. Conservancy. I was especially impressed with the interior of one of the commercial buildings, but unfortunately cannot remember the name. It was exquisite - art deco - with gorgeous green granite, sandstone colored marble, rich wood, beautifully decorated ceilings and light fixtures - breathtaking. There were several buildings as well as a walk through Grand Central Market, The tour ended at the Bradbury Building which has a fascinating history. Its interior has been featured in several motion pictures, the most famous of which is Blade Runner. It is currently an architectural firm - seeing it is believing it. The tour was $10 per person and as the commercial says, it was "priceless". Check out their website laconservancy.org. The tour does involve walking and standing. There was a short period of time when we could sit on a bench at the library or in Pershing Square. There are ample restroom stops. Another good tour would be of the Millennium Biltmore Hotel - we stayed there and it is steeped in Hollywood history. Afterwards, you could enjoy afternoon tea in their lobby.
