Shrewsbury Prison is a former working jail close to the railway station, now opened up for guided and self-guided visits. The appeal is blunt: cells, exercise yards, institutional corridors, and stories of punishment in a town better known for timber-framed streets and river views.
It makes a strong contrast with Shrewsbury's softer historic centre. Go if you are interested in social history or want a less polished attraction; skip it if your time is limited to the abbey, castle, Quarry, and old lanes.
