The walk meandered round the London and Surrey borders keeping close to the Hogsmill River where Millais painted the Death of Ophelia. There are two packhorse bridges over the Hogsmill in Ewell including this one
although neither are medieval both convey history underfoot.
We have met Ewell before on the London Loop and it is a pleasant and interesting town with a 1960s library, Bourne Hall, with a museum. This is where the Hogsmill River rises from springs in the ground forming into ponds. There is a detached church tower and a castle. there is also a remnant of an old justice system in the lock up.
We walked further on to Cheam, (I've been before) and then on to the station and a weary return home.
