Keep a look out on your left here for the Blue Plaque commemorating William Scoresby Snr's house. The plaque is on the wall outside the property - right next to a gate.
Once you've had a good look, keep walking.
Scoresby, the whaling captain, is most well-known for inventing the crow's nest: a platform fixed on the mast of a vessel as a place to look out.
The name crow's nest comes from the Vikings who would sail with caged crows. If they became lost in fog they would release the crows who would instinctively head to the nearest land. By setting their course in this direction, the Viking sailors could avoid becoming lost.
