Captive audience

This cheery sign welcomes you to Dartmoor Prison Museum. Bleak and dark, even on a sunny day, Dartmoor prison is the major establishment of Princetown, high up on Dartmoor in Devon. It was built for French soldiers taken prisoner during the Napoleonic wars in the early 1800s. Bleak though it is, it must have been better than the cramped prison ships it replaced, which were anchored at nearby Plymouth and rife with disease. American prisoners started arriving in 1813 and Dartmoor soon became overcrowded. Outbreaks of typhoid, pneumonia and smallpox killed over 11,000 prisoners. Once the wars with France and America were over, Dartmoor prison was used for domestic convicts from 1850 and is still in use today. The prison museum is worth a visit - crammed full of history and detail. You get a friendly welcome, and some of the staff are prisoners helping out before they move to an open jail. The prisoners are no longer dangerous criminals working in chain gangs breaking stone on the harsh Dartmoor landscape; instead, they are low category prisoners who are encouraged to do training and learn skills to help them when they are released.

Ghost sign in South Brent, Devon. Well, if you live in a village, you've all got to muck in, haven't you? Let's hope the trades didn't get muddled ....

Usual toll applies

There's a bewildering list of tolls on this sign on the Old Toll House in the village of South Brent, Devon. Reading this, I think I understand where our complex tax laws come from. I particularly like the catch-all "For every stall exposing article of whatsoever description for sale" - the usual toll, of course, applies. The toll house dates from the late 18th or early 19th century and is a grade II listed building.

Pioneering picture taking

A visit to the Rochdale Pioneers Museum today reminded me that I had a picture of this rather fine old co-op sign, taken on holiday in Devon last summer.

The museum has a great exhibition of photos of co-op signs – old, new and international. It’s on until 28 February 2015. Catch it if you can, and follow it on #coopography.
