Flag of Castello di Domagnano, a white and light blue horizontal bicolor with the municipal coat of arms centered and the name set vertically at the hoist.
The flag represents the Castello di Domagnano in San Marino. Its coat of arms is divided horizontally, with a gold chief bearing a black lion rampant and a blue base showing three silver towers, symbols of the community’s historic strength, independence, and fortified settlements. The gold, black, blue, and white palette echoes San Marino’s national colors. The banner was adopted in the late 1990s during the standardization of the flags of the nine castelli.
