In brief
Conservation concerns the entire settlement and the surrounding area, not just individual houses.
Useful to know
Hollókő is a consciously preserved traditional settlement, developed mainly in the 17th-XVIII century. UNESCO sees it as a testament to rural life before the agricultural conversions of the 20th century. [1]
For observation, compare the individual house to the street row and the spaces around it. The residential type is understood by repetition and small differences, not only by the most decorated example. When the dating is known, it should remain part of the description, even if the appearance of the village creates a sense of a more distant past.
