A guild hall of the Guild of Merchants in Anvil's middle class district. This guildhall should have rich private accommodations for the guildmaster and shared middle-class accommodations for the lower-ranking members, a number of desks and work areas, and a records room.
Note that this claim is only for the foreground building (with corners marked by green dots).
From Infragris' minor guilds document:
Not so much a trade guild as a professional syndicate, the Merchants Guild originated in the regions of the Iliac Bay before being chartered and instituted across Cyrodiil by the early Septim Emperors.
Initially, the guild was intended to regulate trade across the Empire and to award traders the formal status of merchant according to a complicated system which was to determine their jurisdictions and trade rights. Today the Merchants Guild mainly operates as a rent-seeking organization in major trade cities. The idea that all traders and shopkeepers across the Empire are guild-licensed is laughable. Powerful, politically influential merchant companies such as the EEC or House Hlaalu consider themselves wholly exempt and openly flout guild regulations.
The Merchants Guild awards the status of merchant to anyone who can pay a fee of minimum 600 Drakes (with more required for higher ranks to a maximum of 50,000) and an annual guild tax on stated capital. According to the size of these fees, a member is granted the right to perform retails sales in towns and districts, to own shops and hire employees, to transport goods by land and water, to own workshops and manufacturies, river barges or oceangoing ships, and to trade on a domestic, interprovincial, or even intercontinental level. Members in good status are awarded a non-hereditary rank in the Heartlander merchant-nobility, as well as a small golden anvil, a coveted status symbol among the Empire’s mercantile elites.
While its grip on interprovincial trade is doubtful, the guild does affect certain common commercial standards. They influence minimum and maximum prices for common trade goods, and set the standard for opening and closing hours of shops and the observance of public holidays.
