City Forms and Urban Evolution: A Look at Spanish Development

Urban Morphology: Understanding City Form

Urban morphology describes the external appearance that a city displays. Key elements include:

• The Site: The specific geographical area on which a city is built, influenced by topography and the original function for which the city was created.
• The Situation: The city's position within a wider geographical area, considering its regional context.
• The Urban Plan (Map): The arrangement of a city's free (open) and built-up areas. Common types include radiocentric, irregular, and orthogonal grid (or checkerboard) plans. This also encompasses the construction and overall urban fabric.
• The Plot: Refers to the arrangement of buildings, which may be compact (closed) or open. Buildings themselves can be multi-family or single-family.
• Land Use: The various ways urban space is utilized, such as residential, commercial, industrial, or recreational.

Urban Structure: The Evolution of Spanish Cities

As a result of extensive urbanization, the Spanish city has developed a complex structure. In conventional cities, or those individualized from the surrounding countryside, these areas typically include the old town, areas expanded during the industrial era, and the current periphery. The intensity of urbanization has led to population centers connecting, forming vast urban agglomerations.

The Pre-Industrial City: The Old Town

The old town represents the urbanized core of a city from its origins up to the industrialization of the 19th century. It encompasses disparate elements belonging to different historical stages.

Characteristics of the Old Town

Historically, these areas were often surrounded by walls. The urban fabric was typically closed, dominated by low-rise family houses with yards and gardens. Churches, mosques, and town councils were central features. Land use was diverse, with housing mixed alongside retail shops, stores, and public buildings. Socially diverse groups coexisted within these city centers.

Historical Urban Forms in Spain

• The Roman City: Usually featured a regular, orthogonal plan derived from military camps.
• The Medieval City: Most Spanish cities' old cores were configured during the medieval period.
  • Muslim City: Often a walled nucleus containing the most emblematic buildings. Worker districts were typically located outside these walls. The street layout was very irregular with narrow, winding streets.
  • Christian City: Also surrounded by walls, its plan was often irregular, radiocentric, linear, or checkerboard. Its most prominent buildings included palaces, churches, and noble residences.
• The Renaissance City: Saw the creation of new neighborhoods with regular plans beyond the ancient gates. The Plaza Mayor (main square), often serving as a market, became a central feature.
• The Baroque and Enlightenment City: Cities were embellished with the creation of grand, straight streets, large perspective squares, wooded gardens, and walkways. Monumental religious and civil buildings were constructed.

Key Urbanization Terms

• Urbanization Rate: The percentage of the urban population in relation to the total population.
• Suburban Area: A transitional strip with imprecise boundaries, where land uses and lifestyles characteristic of both rural and urban areas mix.
