Longleat Pleasure Walk, Wiltshire
Longleat Pleasure Walk was designed by Capability Brown in the mid 18th Century, when the parkland was also redesigned, it is usually open to the public, for free, when Longleat itself is open, accessed from the village of Horningsham, or from near Longleat House. As well as mature trees from various parts of the world there are sculptures commissioned by Alexander, the late 7th Marquess of Bath, including the especially weird 'A Woman With Love Money and Death Residing Within Her Soul' by N Rumming, yeah, also a birthing (?) called 'Motherhood' by Erdogan Okbay.
Wheelchair access around the barrier is narrow, though I've done it, but the surface other than around the barrier is good being all tarmac. Heavy enrance gate.
