Ærøskøbing is the island's old merchant town and one of the best-preserved small towns in northern Europe. The streets are cobbled, the doorways are low, and the timber-framed houses lean gently against each other in lines of yellow ochre, deep red, and washed pink. There is no medieval centre and no industrial fringe — just a few crooked streets that have looked roughly the same since the 1700s.
Walk along Vestergade and Søndergade in the early evening, when the day-trippers have left and the houses glow under the streetlamps. Many of the buildings are private homes, several are available for weekly rental, and a handful have been turned over to small museums and craft shops. The ferry from Svendborg arrives directly in the harbour, so the first impression is immediate.
