Horsham is famous for Christ's Hospital but that has its own station. I called there in the afternoon and stayed until evening. Horsham hides well and the signs to direct one to the town centre via park are not always accurate. But the town is old and has some interesting artworks around.
The Registry office in the park has a sundial in fromt of it in a rather nice garden
There is also a swimming pool and gymnastic centre in the park and kinetic sculpture around the town. THis ball gradually fills up with water on the way down, releases it and begins to rise again. To the delight of kids of course!
The museum is extensive with a lot of collections with real old stuff! It's rather typically a small town museum that does not say a lot about the town's uniqueness - perhaps Horsham isn't that unique. They had also run out of self guided walk/town trail leaflets when I called.
The church was locked when I called but apparently is good inside, and genuinely old. Made from ironstone and roofed with horsham stones it looked good from the outside, alas unphotographable.
Thr road to the church was lined with old worlde cottages such as these .
