Keyword & search research

Topic and page planning for this guide was informed by keyword and search-intent research (Serpstat), used to identify the questions real visitors search for most, so we could make sure this guide actually answers them.

A note on accuracy

We've made every reasonable effort to cross-check facts across multiple sources and to credit official information directly to Cadw. That said, we are not the official custodian of the castle, and details — especially prices, hours and facilities — can change without notice. Where accuracy matters most (booking a visit), always confirm directly with Cadw's official page.
