Ginnel

An alley or alleyway is a narrow lane, path, or passageway, often reserved for pedestrians, which usually runs between, behind, or within buildings in the older parts of towns and cities. It is also a rear access or service road (back lane), or a path or walk in a park or garden.

A covered alley or passageway, often with shops, may be called an arcade. The origin of the word alley is late Middle English, from Old French: alee "walking or passage", from aler "go", from Latin: ambulare "to walk".

The word alley is used in two main ways:

In older cities and towns in Europe, alleys are often what is left of a medieval street network, or a right of way or ancient footpath. Similar paths also exist in some older North American towns and cities. In some older urban development in North America lanes at the rear of houses, to allow for deliveries and garbage collection, are called alleys. Alleys and ginnels were also the product of the 1875 Public Health Act in the United Kingdom, where usually alleys run along the back of streets of terraced houses, with ginnels connecting them to the street every fifth house. Alleys may be paved, or unpaved, and a blind alley is a cul-de-sac. Modern urban developments may also provide a service road to allow for waste collection, or rear access for fire engines and parking.

Because of geography, steps (stairs) are the predominant form of alley in hilly cities and towns. This includes Pittsburgh (see Steps of Pittsburgh), Cincinnati (see Steps of Cincinnati), Minneapolis, Seattle, and San Francisco in the United States, as well as Hong Kong,Genoa and Rome.
