This cache is placed across the road (Aylestone Road) from the remains of a Roman Aqueduct, 'The Raw Dykes Monument'. Its a scheduled monument, hence this cache is located on the other side of the road. OK, this monument is really just a ditch, but you can get close and its an interesting distraction for kids.
Taken from the Leicester City Council Website 'The Raw Dykes Monument is located just to the west of Aylestone Road, nearly opposite its junction with Saffron Lane. The current earthworks are a fragment of very much larger works. The surviving stretch of the Raw Dykes is about 100 metres of linear earthworks comprising two parallel earthen banks (double vallum) with a channel (Fosse) measuring about 6 metres between them. The height of the bank varies between 4 and 7 metres. The site is currently fenced off, but can be viewed from Aylestone Road.'
