Urban Patterns | London, United Kingdom

Urban Patterns | London, United Kingdom
by Dr. Mark David Major, AICP, CNU-A

London is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the southeast of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London’s ancient core, the City of London, largely retains its +square-mile medieval boundaries. Since at least the 19th century, “London” has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. London is a leading global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism, and transportation. London has a diverse range of people and cultures, and more than 300 languages are spoken in the region. The estimated mid-2015 municipal population (corresponding to Greater London) was 8,673,713, which is the largest of any city in the European Union, and accounting for 12.5% of the UK population (Source: Wikipedia).

Archaeological discoveries in the London area have found evidence of structures that date back as far as 4,500 B.C., indicating humans have occupied the area far longer than previously thought. However, the founding of London by the Romans in 43 AD still marks the first large-scale settlement in the area. This settlement was founded in the location of the modern “Square Mile” of the City of London (to the right of the below satellite view, north of the River Thames where there are five bridges).

The City of Westminister (west and south of St. James Park along the River Thames where it has a – more or less – north-south alignment at this location) predates the Norman Conquest of England in 1066. The two distinct settlements only began to merge together during the 16th century (see above).

This created a new urban focus in what is now called the West End (the exact center of this image, which is focused on Piccadilly Circus, adjacent to Hyde Park) and, specifically, Oxford Street (the clearly visible, long east-west street at the center of the image). The City of London is characterized by a small-scale, deformed grid pattern of small blocks and short streets (in relative terms, though not nearly as small-scale as during the Medieval period).

In fact, all of London has a deformed grid pattern radiating outward from center-to-edge whereby the scale of the grid became larger for street lengths and block sizes (such as in the West End) during the growth of the city in order to mediate the relationship between the center and its ever-expanding edges.

NOTE: As any Pink Floyd fan might expect, the flying pig marks the location of Battersea Power Station, currently and finally being redeveloped.

Urban Patterns | Vienna, Austria

“Now in Vienna there are ten pretty women,
There’s a shoulder where Death comes to cry.”

Urban Patterns | Vienna, Austria
by Dr. Mark David Major, AICP, CNU-A

Vienna is the capital and largest city of Austria with a population of about 1.8 million (2.6 million within the metropolitan area, nearly one-third of Austria’s population), and its cultural, economic, and political center. It is the 7th-largest city by population within city limits in the European Union. There is evidence of continuous habitation in Vienna since 500 BC when the site on the Danube River was first settled by the Celts. In 15 BC, the Romans fortified the frontier city they called “Vindobona” to guard the empire against Germanic tribes invading from the north. Vienna is known for its high quality of life. In a 2005 study of 127 world cities, the Economist Intelligence Unit ranked the city first (in a tie with Vancouver, Canada and San Francisco, USA) for the world’s most liveable cities (Source: Wikipedia).

The urban layout of Vienna is a classic European deformed grid with a series of open-angled diagonal routes radiating outward from center-to-edge and intersecting/overlaying with a series of ring/orbital roads, which similarly radiate outwards based on an increasing radius from center-to-edge, i.e. smaller rings in the center, successively larger in the periphery. As in other European cities, the deformed grid pattern in the oldest area of the city (more or less center above) is composed of smaller blocks and shorter streets. As the city has grown in size, the size of blocks and length of streets (and associated segments) have increased, which embeds the layout with a strongly consistent geometric logic (especially when blocks are examined in discrete terms) in its deformed grid pattern.

Urban Patterns | Ulaanbaatar, Mongolia

Urban Patterns | Ulaanbaatar, Mongolia

Ulaanbaatar, Mongolia is a fascinating settlement for a variety of reasons. The city was founded in 1639 as a movable (i.e. nomadic) Buddhist monastic center. In 1778, it settled permanently in its present location at the junction of the Tuul and Selbe rivers. Before that, it changed location 28 times with each site selected for ceremonial reasons (Source: City of Ulaanbaatar). At first glance from 60,000 feet (see above), the urban pattern appears to be strongly characterized by a predominantly linear structure oriented to the Tuul River, the Trans-Siberian railway line, and Peace Avenue, all of which (more or less) runs parallel to each other in an east-to-west direction. However, this is somewhat misleading due to radical differences in building scale between (mainly) residential areas in the periphery and the non-residential areas of the settlement in the city center. This is clearer in a view of the settlement from 20,000 feet (see below), which reveals the street network is actually a deformed grid layout, very characteristic of European towns. The difference in the scale of building construction in the city center (large buildings and blocks) compared to the surrounding residential areas (small buildings in elongated blocks) is quite distinctive.

Closer examination of a residential area reveals a reason for the radical differences in building scale in the settlement (see below view from 6,000 feet). The residential area is characterized by walled compounds, many of which have a yurt (circular structure generally in white in the below image). A yurt is a portable, bent dwelling structure traditionally used in nomadic cultures from the steppes of Central Asia. The structure comprises a crown or compression wheel usually steam bent, supported by roof ribs which are bent down at the end where they meet the lattice wall (again steam bent). The top of the wall is prevented from spreading by means of a tension band which opposes the force of the roof ribs. The structure is usually covered by layers of fabric and sheep’s wool felt for insulation and weatherproofing (Source: Wikipedia). Many of the compounds also have a permanent structure, which tends to have colorful roofs. All of these physical features, combined with the nomadic origins of the settlement, makes Ulannbaatar one of the most fascinating urban patterns on our planet.
