Our village rookery

"Rookery" was a colloquial term given in the 18th and 19th centuries to a city slum occupied by poor people and frequently also by criminals and prostitutes. Such areas were overcrowded, with low-quality housing and little or no sanitation. Poorly constructed dwellings, built with multiple storeys and often crammed into any area of open ground, created densely-populated areas of gloomy, narrow streets and alleyways.

The nickname rookery originated because of the perceived similarities between a city slum and the nesting habits of the rook, a bird in the crow family. Rooks nest in large, noisy colonies consisting of multiple nests, often untidily crammed into a close group of treetops called a rookery.
