Christianshavn is the Dutch-style canal town Christian IV laid out in 1617 on the eastern side of the inner harbour, fortified to defend the city. The merchant houses on Strandgade are the seventeenth century; the houseboats on Wilders Kanal are the present; the golden spiral spire on Vor Frelsers Kirke is the photograph everyone takes.
Three kilometres, ninety minutes, with the climb. Christianshavn metro (M1/M2) lands you at the centre. Christianshavns Torv is the village square — bicycle traffic, cafés, the daily rhythm of a working neighbourhood. South across Wilders Kanal to Strandgade, where the 17th-c merchant houses still face the inner harbour.
The church is the spire. Vor Frelsers Kirke is 1696; the famous golden spiral was added in 1752 — Lauritz de Thurah's outdoor staircase climbing counter-clockwise to the top, four hundred steps and the best view of the harbour available without a helicopter. Check before you go; restoration closes it intermittently.
End at Wilders Plads — a small square on the canal, cafés in old warehouses, houseboats moored along the quay. Five minutes back to the metro.
