I never realised that it is the new parts of Riga
that are the basis for its inscription. I knew the Art Nouveau there was impressive, but from reading the evaluation
this is the main reason for its inscription.
The evaluation doesn't categorically state it is on a grid plan
, but goes to lengths to stress the wide boulevards and rational layout, and if you look it is definitely on a grid plan (except the core of the old town, but these are only additional to the new aspects that form the core of the OUV).
From what I remember of Essaouira
it was a lot more rational than any other medina I have visited, it is also based on St Malo which is on a rigid grid plan. Having had a look at the evaluation
it mentions the checker board layout, and something called the Cornut Plan
relating to the architect/ mathematician
and his implementation of a grid plan at Essaouira.Kerkuane
is a little tougher. It certainly is logically planned and the buildings are mostly rectangular. However if you look at the plan of the ruins
you can see there are curved and some clusters of buildings don't fit the overall pattern. Personally I think it is a reasonable to think of it as a grid. Incidentally this is a lovely little site to visit I would thoroughly recommend heading there if you are in Tunisia
That grid plan one could turn into a bit of a monster. Most colonial towns (ancient - modern) will be on grid plans.
Just off the top of my head I can think of: Beemster, Krakow, Mohenjo-daro, Gyongju (if bits of the town are covered), Pingyao, Hue, Angkor,Ile St Louis, Grand Bassam, Quito, Mexico City, Carthage, Lima, Saltaire, Berlin Modernist Estates, Crespi d'Adda, Siracusa, Val di Noto, Lyon, Gaudi Buildings (l'Eixample is a key example of grid planning
), Tel Aviv ? (not sure on that one), Carcassone, Pompei, Naples, Castles of Gwyndd...
I could go on, so not sure if we want to have a stricter definition, or want to go whole hog and have everything that is on a grid plan, which could be a bit of a task, but perhaps worthwhile.
