As Krk has a strict regime on construction activities, the historic (aka 19th century) appearance of its structure is mostly intact inside the city walls. The houses are of similar height and irregular floor plan and the walls richly structured. Thus the interesting play of shadows everywhere. The challenge for the council now will be to find the right balance between the justified demands of the population for more comfort and the demands of tourism to retain that pittoresque appearance. At the moment there is an unlimited spread of ACs everwhere, which will certainly damage the attractivity of the city if not channeled where necessary.
