I would like to get on and post about my walk on Feb 2nd (another lovely, clear, fresh sunny winter's day) but maybe I should take a moment to answer some of thew questions I have raised in the past, and Steve Grindlay answered so eloquently.
1. The house I spotted opposite the junction of Honor Oak Road and London Road (across from the Horniman Museum) was the property of "A & G Taylor" and I believe was called Forest Lodge. "A&G" (to their mates) were probably the leading Victorian photographers of "Cartes de Visite", a sort of postcard plus means of correspondence of the age. A little like today's MMS text messages, just for quick notes. More on them in future I hope.
2. The avenue of trees I found leading off Honor Oak Road after Hamilton Hall do not lead to a disused railway, but a reservoir. I suspect it is derelict now, but as it is totally enclosed, and residents have succesfully fought off the developers, it is another "secret garden". I MUST get in here for a look. Can anyone help?
Steve also told an interesting story of how this reservoir (built at the end of the 19th century) influenced a then young boy who became a great poet. Unfortunately my knowledge of this art form, beyond the Owl and the Pussycat, is extremely limited so I didn't catch the name. Another one for the future.
3. The bottom of Manor Mount, where the ambulance station is, has a strange building backing on to it. I always thought it looked vaguely nautical (round windows, made of wood, with a big balcony, etc.). It turns out that the whole area was the basin for the canal that ran through here, so I need to find out whether that building is contemporaneous. (Nice word, hard to spell.)
4. Much of the area behind the Horniman Museum was owned by a single family (I promise to find out the name I have already forgotten) who might even have considered offering it as another extension to the Horniman Gardens (now THAT would have been impressive). This area is known as Tewkesbury Lodge. However, they didn't and it has since been developed. The only remnant of their massive Lodge is the folly that had been built in the garden to take advantage of the beautiful views. This still remains, and it remains a place I need to try and get to visit. Unfortunately it is in someone's private garden now.
5. And finally, although Christ Church on South Road is being redeveloped (slowly) as flats, a few of the remaining monuments from the graveyard remain. These are important historical references to the Tetley (tea) family, the (Lea &) Perrins family, a wealthy merchant called Chaplin (no relation to ol' Charlie) and one or two more. All these people lived, died and came to rest in Forest Hill. If you happen to buy one of those flats, think about that when you next boil the kettle!
More updates and clarifications soon.
