Frequently asked questions
- How many forts are in this guide?
- We currently list 564 forts across the United Kingdom — every entry sourced from Wikipedia, Wikidata or OpenStreetMap and validated against our schema.
- Are these places free to visit?
- Many places in the guide are free to enter — almost every national museum, every public park and garden, every parish church and cathedral. Castles, historic houses and theme parks usually charge admission; National Trust and English Heritage members visit those properties free.
- Where does the data come from?
