In 1961, Klagenfurt became the first city in Austria to adopt a pedestrian zone. The idea of a friendly twinning of cities in other countries began with the very first-ever city partnership between Klagenfurt and Wiesbaden, Germany, as early as 1930. This was followed up by numerous city partnerships, with the result that in 1968, Klagenfurt was honoured with the title of "European City of the Year". Klagenfurt has also been awarded the prestigious Europa Nostra Diploma of Merit (an award for the exemplary restoration and redevelopment of its ancient centre) a total of three times, which is a record for a European city.
