The Market is a 13th-century building used to buy and sell resources. The Market has several abilities; in addition to buying and selling resources (on a silver standard), you can train Merchants, research technologies to speed up your merchant units, decrease the trading fee, and give tributes to other players (and reduce, and eventually eliminate, the extra cost to doing so).
