More for my own records than for public consumption – but, hey, feel free to peruse below the cut – here is my World Heritage sites roster, with links to my posts that contain relevant pictures. Links to UNESCO list inscriptions are provided as well, along with the year each site was added (in parenthesis).
I am using a liberal – and not entirely consistent – definition of “visited” for the purposes of this list. Basically, any site that I made a concerted effort to explore within the limits of accessibility counts as having been visited. For a geographical entity – such as a square, a city area, or a region – that is a simple criterion. For a historical or architectural monument, it gets more complicated: If interior access is possible, the site cannot be counted unless I stepped inside (as well as did not bypass the singular primary subject for which the monument is recognized, if such is clearly identified); conversely, if interior access is prohibited or allowed on rare basis, the site can be counted if I expressly stopped by to take photographs of its exterior.
The serial sites are counted if at least one part of it can be counted according to the loose definition above.
