A pinnacle (from Latin pinnaculum, a little feather, pinna, compare panache) is an architectural ornament originally forming the cap or crown of a buttress or small turret, but afterwards used on parapets at the corners of towers and in many other situations. The pinnacle looks like a small spire. It was mainly used in Gothic architecture.

The pinnacle had two purposes:

Some^[who?] have stated that there were no pinnacles in the Romanesque style, but conical caps to circular buttresses, with finial terminations, are not uncommon in France at very early periods. Viollet-le-Duc gives examples from St Germer and St Remi, and there is one of similar form at the west front of Rochester Cathedral.

In the 12th-century Romanesque two examples have been cited, one from Bredon in Worcestershire, and the other from Cleeve in Gloucestershire. In these the buttresses run up, forming a sort of square turret, and crowned with a pyramidal cap, very much like those of the next period, the Early English.

In this and the following styles, and mainly in Gothic architecture, the pinnacle seems generally to have had its appropriate uses. It was a weight to counteract the thrust of the vaults, particularly where there were flying buttresses; it stopped the tendency to slip of the stone copings of the gables, and counterpoised the thrust of spires; it formed a pier to steady the elegant perforated parapets of later periods; and in France especially served to counterbalance the weight of overhanging corbel tables, huge gargoyles, etc.

A bank is a financial institution and a financial intermediary that accepts deposits and channels those deposits into lending activities, either directly or through capital markets. A bank connects customers that have capital deficits to customers with capital surpluses.^{[citation needed]}

Due to their critical status within the financial system and the economy^{[citation needed]} generally, banks are highly regulated in most countries. Most banks operate under a system known as fractional reserve banking where they hold only a small reserve of the funds deposited and lend out the rest for profit. They are generally subject to minimum capital requirements which are based on an international set of capital standards, known as the Basel Accords.

The oldest bank still in existence is Monte dei Paschi di Siena, headquartered in Siena, Italy, which has been operating continuously since 1472.

Banking in the modern sense of the word can be traced to medieval and early Renaissance Italy, to the rich cities in the north like Florence, Venice and Genoa. The Bardi and Peruzzi families dominated banking in 14th century Florence, establishing branches in many other parts of Europe. Perhaps the most famous Italian bank was the Medici bank, set up by Giovanni Medici in 1397. The earliest known state deposit bank, Banco di San Giorgio (Bank of St. George), was founded in 1407 at Genoa, Italy.

An arena is an enclosed area, often circular or oval-shaped, designed to showcase theater, musical performances, or sporting events. The word derives from Latin harena, a particularly fine/smooth sand used to absorb blood in ancient arenas like the Colosseum in Rome. It is composed of a large open space surrounded on most or all sides by tiered seating for spectators. The key feature of an arena is that the event space is the lowest point, allowing for maximum visibility. Usually, an arena is designed to accommodate a fairly large number of spectators.

The term arena is sometimes used as a synonym for a very large venue such as Pasadena's Rose Bowl, but such a facility is typically called a stadium, especially if it does not have a roof.^{[citation needed]} The use of one term over the other has mostly to do with the type of event. Football (be it association, rugby, or gridiron) is typically played in a stadium while basketball and ice hockey are typically played in an arena, although many of the larger arenas hold more spectators than do the stadiums of smaller colleges or high schools. There are exceptions. The home of the Duke University basketball team would qualify as an arena, but the facility is called Cameron Indoor Stadium. Domed stadiums, which like arenas are enclosed but have the larger playing surfaces and seating capacities found in stadiums, also fall under a gray area. There is also the sport of indoor American football (one variant of which is explicitly known as arena football), a variant of the gridiron-based game that is designed for the usual smaller playing surface of most arenas; variants of other traditionally outdoor sports, including box lacrosse and futsal/indoor soccer, also exist.
