Holmen (Danish: The Islet) is a water-bound neighbourhood in Copenhagen, Denmark, occupying the former grounds of the Royal Naval Base and Dockyards. In spite of its name, deceptively in singular, Holmen is a congregation of small islands, forming a north-eastern extension of Christianshavn between Zealand and the northern tip of Amager. Though technically a part of the central Indre By district of Copenhagen, being a cul-de-sac as districts go, the area has a somewhat quiet and "remote" reputation and feel to it.
