Yes, it's a bit too "touristy", but surely it's worth a visit! It's a tiny backyard of old houses built in the 17th century and perfectly restored. They were built as retirement homes for the widows of storekeepers which couldn't carry on their husband's work by the law. They were still used until the '60s. Now there are almost all souvenirs shops, a restaurants and some art galleries.
In 1620 in Krayenkamp stood a pleasure gardens with country house and summer house. In 1676 the Krameramt (Guild of Small Traders) acquired the site and erected two rows of terrace-houses facing each other across a narrow lane. Each terrace consisted of five two-storeyed half-timbered houses with flats for the widows of small traders. After the introduction of freedom of trade in 1866 the city acquired the buildings and they were turned into old people's flats. From 1971 to 1974 ensued drastic repairs and restoration. The twisted chimneys are an original architectural detail of the buildings.
Today the road is full of souvenir shops, restaurants and some art galleries. Despite the hordes of tourists you do get an idea of what it was like back in the 17th century.
The Krameramtswohnungen is an old complex of apartments dating from 1676 and now you can visit some souvenirs shops and restaurants.
