TODO for editor: Introduce Castlebook as a worldwide directory for discovering castles to visit — with practical visiting guides, history, and photos — and for finding castle hotels and nearby stays. Mention that listings grow across continents and that event inquiries for estate owners remain available without making weddings the primary story.

TODO for editor: Briefly explain how travellers browse by region and country, open a castle page for visitor details when available, and how owners can claim or add an estate. Keep the tone factual; no invented statistics beyond live site counts shown elsewhere on the homepage.
