<p>A&nbsp;<strong>mansion</strong>&nbsp;is a large dwelling&nbsp;house.</p>
<p>The word itself derives through&nbsp;Old French&nbsp;from the&nbsp;Latin&nbsp;word&nbsp;<em>mansio</em>&nbsp;"dwelling", an abstract noun derived from the verb&nbsp;<em>manere</em>&nbsp;"to dwell". The&nbsp;English&nbsp;word "manse" originally defined a property large enough for the parish priest to maintain himself, but a mansion is no longer self-sustaining in this way (compare a Roman or medieval&nbsp;villa). 'Manor' comes from the same root&mdash;territorial holdings granted to a lord who would&nbsp;<em>remain</em>&nbsp;there&mdash;hence it is easy to see how the word 'Mansion' came to have its meaning.</p>
<p>Within an&nbsp;ancient Roman&nbsp;city, patrician&nbsp;dwellings&nbsp;might be very extensive, and luxurious. Such mansions on one hill in&nbsp;Rome&nbsp;became so extensive that the term&nbsp;palatial&nbsp;was actually derived from the name&nbsp;Palatine hill&nbsp;and is the etymological origin of "palace".<sup id="cite_ref-1" class="reference"><br /></sup></p>

<p>Following the fall of Rome the practice of building unfortified villas ceased. Today, the oldest inhabited mansions around the world usually began their existence as fortified&nbsp;castles&nbsp;in the&nbsp;middle ages. As social conditions slowly changed and stabilised&nbsp;fortifications&nbsp;were able to be reduced, and over the centuries gave way to comfort. It became fashionable and possible for homes to be beautiful rather than grim and forbidding allowing for the development of the modern mansion.</p>
<p>In British English a&nbsp;<strong>mansion block</strong>&nbsp;refers to a block of flats or&nbsp;apartments&nbsp;designed for the appearance of grandeur. In many parts of Asia, including Hong Kong and Japan, the word mansion also refers to a block of apartments.</p>
<p>In Europe, from the 15th century onwards, a combination of politics and advancements in modern weaponry negated the need for the aristocracy to live in fortified castles. As a result, many were transformed into mansions without defences or demolished and rebuilt in a more modern, undefended style. Due to intermarriage and primogeniture inheritance amongst the aristocracy, it became common for one noble to often own several country houses. These would be visited rotationally throughout the year as their owner pursued the social and sporting circuit from country home to country home.&nbsp;Many owners of a country house would also own a town mansion in their country's capital city. These town mansions were referred to as 'houses' in London, hotels in Paris and palaces in most European cities elsewhere. It might be noted that sometimes the house of a clergyman was called a "mansion house" (e.g.by the Revd James Blair, Commissary in Virginia for the Bishop of London, 1689-1745, a term related to the word "manse" commonly used in the Church of Scotland and in Non-Conformist churches.
