To Sintra and Queluz in Portugal, to visit historic palaces and created landscapes. Sintra Cultural Landscape World Heritage Site is managed by Parques de Sintra, who have created new and very effective interpretation of the whole World Heritage Site and buffer zone, at Pena Palace.  It is a 3D topographic model, onto which you can project rock types, contours, rainfall, etc, to understand how these create the favourable climate and dramatic scenery.

Parques de Sintra has an "Open for works" policy at its historic buildings, so that visitors can get close to see the conservators at work.

The forest around Pena Palace was created from a bare hillside in the 19th century - like Cragside in Northumberland or Inverewe in Scotland - with over 500 exotic species from around the world. 

Good discussions with staff at Sintra, Pena and Queluz about the challenges of interpreting busy sites to visitors of many nationalities, and agreeing that short text panels are definitely better than long ones!
