Bristol, the largest city in South West England, has an eclectic combination of architectural styles, ranging from the medieval to 20th century brutalism and beyond. During the mid-19th century, Bristol Byzantine, an architectural style unique to the city was developed, of which several examples have survived.
Buildings from most of the architectural periods of the United Kingdom can be seen throughout Bristol. Parts of the fortified city and castle date back to the medieval era, as do some churches dating from the 12th century onwards. Outside the historical city centre there are several large Tudor mansions built for wealthy merchants. Almshouses and public houses of the same period survive, intermingled with areas of more recent development. Several Georgian-era squares were laid out for the enjoyment of the middle class. As the city grew, it merged with its surrounding villages, each with its own character and centre, often clustered around a parish church.
