this place deserves a post of it's own.
we're staying 5 minutes walk from Nyhavn and it was one of the first places i caught a glimpse of when we first arrived. i'd always seen pictures but it was far more beautiful in person.
Nyhavn was constructed by King Christian V and the oldest house dates from 1661. it was notorious for beer, sailors, and prostitution - it's the old red light district for Copenhagen.
Danish author Hans Christian Andersen lived at Nyhavn 18 for many years and we were told the reason for the brightly painted buildings was so that when the sailors came home drunk, they knew which house was theirs.
