In the last of the series, the writer returns to three passed-over places where he used to live – Harrow, Clitheroe and Princetown in Devon

• Where tourists seldom tread, parts 1-19

The last in this series of underexplored, overlooked, bypassed towns revisits three places loosely linked to somewhere I’ve lived at different stages of my life. Relocating is grand-scale vacationing, as there are a few months when the new place feels like a holiday destination – fresh, strange, not filtered and tainted by habit or prejudice. Going back years later is part-pilgrimage, part-funeral.
