I visited this WHS in June 2015. This is one of many other WHS made up of gardens and palaces and it certainly isn't one of Europe's best. It's location helps it a great deal as it is a pleasant half day trip from Madrid or Toledo. However, I very much prefered the Escurial's interior although much more crowded. The highlights of my visit were the Island Garden and the Prince's Garden. That said, I felt that they offered no real OUV but more of a pleasant rest in the shade in what should be considered more of a national heritage site.
