Vor Freslers Kirke, or Our Savior's Church, is fantastic! You can catch Wednesday evening or Sunday organ concerts. Even when it's not playing however the ornamental pipes alone are breathtaking. The Church’s highlight though is the spire, a quintessential piece of the city skyline. You can walk up the lined spiral stairs on the outside of the tower and the top offer one of the best views of Copenhagen. It closes down on windy and rainy days and usually a bit early in winter since the sun sets so early, but it is worth the hike up every step to see the city's red roof's and waterways. It is easy to get to by bike or located just a block or so from the Christianshavn Metro.
