Visitor tips

  1. 1

    Allow about 120 minutes for a normal visit, with extra time for photographs, queues, worship, interpretation or rest.

  3. 3

    Dress respectfully at active religious and memorial sites and avoid disrupting worship, funerals or commemorations.

  4. 4

    Combine this stop with nearby places in the same region to reduce backtracking and parking searches.

    Check local events and religious times because access and crowd levels can change without appearing in old travel listings.
