situated on the city's perimeter, near the amphitheatre. A long narrow building at the north-west corner of the Forum was some type of market, possibly a cereal market. On the opposite corner stood the macellum, thought to have been a meat and fish market. Market stall-holders paid a market tax for the right to trade on market days. Some archaeological evidence suggests that markets and street vendors were controlled by local government. A graffito on the outside of a large shop documents a seven-day cycle of markets; "Saturn’s day at Pompeii and Nuceria, Sun’s day at Atella and Nola, Moon’s day at Cumae ... etc." The presence of an official commercial calendar suggests something of the market's importance to community life and trade. Markets were also important centres of social life. In medieval Europe In early Western Europe, markets developed close to monasteries, castles or royal residences. Priories and aristocratic manorial households created considerable demand for goods and services - both luxuries and necessities and also afforded some protection to merchants and traders. These centres of trade attracted sellers which would stimulate the growth of the town. The Domesday Book of 1086 lists 50 markets in England, however, many historians believe this figure underestimates the actual number of markets in operation at the time. In England, some 2,000 new markets were established between 1200 and 1349. By 1516, England had some 2,464 markets and 2,767 fairs while Wales had 138 markets and 166 fairs. From the 12th century, English monarchs awarded a charter to local Lords to create markets and fairs for a town or village. A charter protected the town's trading privileges in return for an annual fee. Once a chartered market was granted for specific market days, a nearby rival market could not open on the same days. Fairs, which were usually held annually, and almost always associated with a religious festival, traded in high value goods, while regular weekly or bi-weekly markets primarily traded in fresh produce and necessities. Although a fair's primary purpose was trade, it typically included some elements of entertainment, such as dance, music or tournaments. As the number of markets increased, market towns situated themselves sufficiently far apart so as to avoid competition, but close enough to permit local producers a round trip within one day (about 10 km). Some British open-air markets have been operating continuously since the 12th century. A pattern
