Architectural form in the context of "Architecture of Ancient Greece"

Ancient Greek architecture came from the Greeks, or Hellenes, whose culture flourished on the Greek mainland, the Peloponnese, the Aegean Islands, and in colonies in Anatolia and Italy for a period from about 900 BC until the 1st century AD, with the earliest remaining architectural works dating from around 600 BC.

Ancient Greek architecture is best known for its temples, many of which are found throughout the region, with the Parthenon regarded, now as in ancient times, as the prime example. Most remains are very incomplete ruins, but a number survive substantially intact, mostly outside modern Greece. The second important type of building that survives all over the Hellenic world is the open-air theatre, with the earliest dating from around 525–480 BC. Other architectural forms that are still in evidence are the processional gateway (propylon), the public square (agora) surrounded by storied colonnade (stoa), the town council building (bouleuterion), the public monument, the monumental tomb (mausoleum) and the stadium.

Form follows function is a principle of design associated with late 19th- and early 20th-century architecture and industrial design in general, which states that the appearance and structure of a building or object (architectural form) should primarily relate to its intended function or purpose.

The architectural form of theatre in Rome has been linked to later, more well-known examples from the 1st century BC to the 3rd Century AD. The theatre of ancient Rome referred to a period of time in which theatrical practice and performance took place in Rome. The tradition has been linked back even further to the 4th century BC, following the state’s transition from monarchy to republic. Theatre during this era is generally separated into genres of tragedy and comedy, which are represented by a particular style of architecture and stage play, and conveyed to an audience purely as a form of entertainment and control. When it came to the audience, Romans favored entertainment and performance over tragedy and drama, displaying a more modern form of theatre that is still used in contemporary times.

'Spectacle' became an essential part of an everyday Romans expectations when it came to theatre. Some works by Plautus, Terence, and Seneca the Younger that survive to this day, highlight the different aspects of Roman society and culture at the time, including advancements in Roman literature and theatre. Theatre during this period of time would come to represent an important aspect of Roman society during the Republican and Imperial periods of Rome.

A cathedral is a church that contains the cathedra (Greek for 'seat') of a bishop, thus serving as the central church of a diocese, conference, or episcopate. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Catholic, Eastern Orthodox, Anglican, and some Lutheran churches. Church buildings embodying the functions of a cathedral first appeared in Italy, Gaul, Spain, and North Africa in the 4th century, but cathedrals did not become universal within the Western Catholic Church until the 12th century, by which time they had developed architectural forms, institutional structures, and legal identities distinct from parish churches, monastic churches, and episcopal residences. The cathedral is more important in the hierarchy than the church because it is from the cathedral that the bishop governs the area under his or her administrative authority.

Following the Protestant Reformation, the Christian church in several parts of Western Europe, such as Scotland, the Netherlands, certain Swiss Cantons and parts of Germany, adopted a presbyterian polity that did away with bishops altogether. Where ancient cathedral buildings in these lands are still in use for congregational worship, they generally retain the title and dignity of "cathedral", maintaining and developing distinct cathedral functions, but void of hierarchical supremacy. From the 16th century onwards, but especially since the 19th century, churches originating in Western Europe have undertaken vigorous programmes of missionary activity, leading to the founding of large numbers of new dioceses with associated cathedral establishments of varying forms in Asia, Africa, Australasia, Oceania and the Americas. In addition, both the Catholic Church and Orthodox churches have formed new dioceses within formerly Protestant lands for converts and migrant co-religionists. Consequently, it is not uncommon to find Christians in a single city being served by three or more cathedrals of differing denominations. For example, London is home to the Anglican St Paul’s Cathedral, the Catholic Westminster Cathedral & St George's Cathedral, and several Eastern Orthodox cathedrals serving different national communities.[1]

In Ancient Roman architecture, a basilica (Greek basilike) was a large public building with multiple functions that was typically built alongside the town's forum. The basilica was in the Latin West equivalent to a stoa in the Greek East. The building gave its name to the basilica architectural form.

Originally, a basilica was an ancient Roman public building, where courts were held, as well as serving other official and public functions. Basilicas are typically rectangular buildings with a central nave flanked by two or more longitudinal aisles, with the roof at two levels, being higher in the centre over the nave to admit a clerestory and lower over the side-aisles. An apse at one end, or less frequently at both ends or on the side, usually contained the raised tribunal occupied by the Roman magistrates. The basilica was centrally located in every Roman town, usually adjacent to the forum and often opposite a temple in imperial-era forums. Basilicas were also built in private residences and imperial palaces and were known as "palace basilicas".

Memorial gates and arches are architectural monuments in the form of gates and arches or other entrances, constructed as a memorial, often dedicated to a particular war though some are dedicated to individuals. The function, and very often the architectural form, is similar to that of a Roman triumphal arch, with the emphasis on remembrance and commemoration of war casualties, on marking a civil event (the country's independence, for example), or on providing a monumental entrance to a city, as opposed to celebrating a military success or general, though some memorial arches perform both functions. They can vary in size, but are commonly monumental stone structures combining features of both an archway and a gate, often forming an entrance or straddling a roadway, but sometimes constructed in isolation as a standalone structure, or on a smaller scale as a local memorial to war dead. Although they can share architectural features with triumphal arches, memorial arches and gates constructed from the 20th century onwards often have the names of the dead inscribed on them as an act of commemoration.
