Santa Marco is a township in the Saint Omar province of St. Samuel. The coastal town is located in the north-west of the province, in the Bay of Uhlan. Santa Marco was founded around 2000BP and was named after Saint Marco Ettiene. The town's extensive waterfront and the naturally sheltered harbour gave rise to its success as a boat, shipbuilding and sailing port and, in modern times, tourism especially in the form of pleasure sailing and yachting. There is also a crabbing and fishing industry. Santa Marco was chosen by the Samuelonian Cycling Federation as the start point for Stage 3 of the Tour of Samuelonia.
