A leafy passageway to the spa town’s Kurhaus. An alley of chestnut trees already existed here before the first windy stalls set up there in 1766. In 1818 they were replaced with more solid wooden booths. Now there are two parallel rows of boutiques selling high quality jewels, fashion and confectioneries, bathed in the shade of the trees. They were built between 1867 and 1868, modelled on the Parisian commercial arcades of the time.
