How the flags work

What we show, and what we leave out

Every flag below comes from a source you can open. Where we hold no report, the list says "not stated" or shows nothing: it does not guess. Check the venue before you travel, because prices, hours and booking rules change.

  • Type. Our own grouping of each place's kind in our destination guides (for example museum, castle or garden). It is a filter, not a rating.
  • Entry (free or paid). Shown only where the venue's own website says so in plain words, read on Oct 25, 2026. 0 places here are marked free and 0 paid; the other 21 are not stated. "Free" means general admission: special exhibitions, events and facilities can still be charged. The words we relied on are on the sources page.
  • Booking. We have not yet read a venue page that advises booking for these places, so there is no booking filter. Check each official site.
  • Step-free. Reported status only, from OpenStreetMap contributors or the venue's own access page: 0 places have a step-free or partly step-free report. The step-free filter hides places with no report; that does not mean they are not accessible. Contact the venue.
  • Indoor or outdoor. Our rules for the kind of place (2 indoor, 0 partly covered, 5 outdoor; the rest are not classed). It says nothing about opening hours or shelter on the day.
  • Family-friendly. Places marked family-friendly in our guides (0 so far).
  • Nearest to me. Straight-line distance from the position your device reports when you choose it. The position stays in your browser.
  • Saved on this device. Places you have saved with the heart. They are kept in this browser only, and appear in My trip.
