Question: What kind of building did the Romans use that is still the most common architectural style for churches in Europe and America?

<P0-S0> The International Style is the name of a major architectural style that is said to have emerged in the 1920s and 1930s, the formative decades of modern architecture, as first defined by Americans Henry-Russell Hitchcock and Philip Johnson in 1932, with an emphasis more on architectural style, form and aesthetics than the social aspects of the modern movement as emphasised in Europe. <P0-S1>  The term "International Style" first came into use via a 1932 exhibition curated by Hitchcock and Johnson, "Modern Architecture: International Exhibition", which declared and labelled the architecture of the early 20th century as the "International Style". <P0-S2>  The most common characteristics of International Style buildings are said to be: i. rectilinear forms; ii. <P0-S3>  light, taut plane surfaces that have been completely stripped of applied ornamentation and decoration; iii. <P0-S4>  open interior spaces; iv. <P0-S5>  a visually weightless quality engendered by the use of cantilever construction. <P0-S6>  Glass and steel, in combination with usually less visible reinforced concrete, are the characteristic materials of the construction. <SEP> <P1-S0> Rosary Church () is located at 125 Chatham Road South, Tsim Sha Tsui, Kowloon, Hong Kong. <P1-S1>  The church is in Gothic style; the original plan was based on a Roman Basilican model. <P1-S2>  It is the oldest Catholic church in Kowloon. <P1-S3>  The church, St. Mary's Canossian College and St. Mary's Canossian School in adjacent belongs to same building cluster. <SEP> <P2-S0> Italy has a very broad and diverse architectural style, which cannot be simply classified by period or region, due to Italy's division into several city-states until 1861. <P2-S1>  However, this has created a highly diverse and eclectic range in architectural designs. <P2-S2>  Italy is known for its considerable architectural achievements, such as the construction of arches, domes and similar structure during ancient Rome, the founding of the Renaissance architectural movement in the late-14th to 16th century, and being the homeland of Palladianism, a style of construction which inspired movements such as that of Neoclassical architecture, and influenced the designs which noblemen built their country houses all over the world, notably in the United Kingdom, Australia and the United States of America during the late-17th to early 20th centuries. <P2-S3>  Several of the finest works in Western architecture, such as the Colosseum, the Duomo of Milan, the Mole Antonelliana in Turin, Florence cathedral and the building designs of Venice are found in Italy. <P2-S4>  Italy has an estimated total of 100,000 monuments of all varieties (museums, palaces, buildings, statues, churches, art galleries, villas, fountains, historic houses and archaeological remains). <P2-S5>  Now Italy is in the forefront of modernist and sustainable design with Architects like Renzo Piano and Carlo Mollino. <SEP> <P3-S0>  In Europe and the Americas it is the most common architectural style for churches though this building plan has become less dominant in new buildings since the later 20th century. <P3-S1>  Today the term "basilica" is often used to refer to any large, ornate church building, especially Roman Catholic and Eastern Orthodox, even if it does not strictly follow this style. <P3-S2> A basilica is a type of building, usually a Christian church, that is typically rectangular with a central nave and aisles, usually with a slightly raised platform and an apse at one or both ends.
