The Muralla Medieval de Barcelona is a surviving remnant of the city's 14th-century defensive wall, located in the Gothic Quarter adjacent to the Maritime Museum. Built as Barcelona industrialized and expanded, sections of this medieval fortification were demolished in the 19th century to enable urban growth. The preserved fragment near les Drassanes offers visitors a tangible connection to Barcelona's medieval past, providing insight into the walled city's historic perimeter and the defensive architecture that once enclosed the urban center.
