Helford village straddles a tidal creek on the southern shore of the Helford estuary. Unlike much of Cornwall this area is densely wooded, and another difference is many of the cottages have thatched roofs. This gives the villages and hamlets of the Helford a chocolate box / picture postcard appearance.
These cottages are set at the foot of the valley right next to where the road bridge is. If I where to guess, I'd say they date back to the 17th/18th century when Helford was a thriving river port.
