Our first stop is at the "Waterfall Garden Park". The waterfall in the courtyard of the former UPS-headquarter, 6.5 meter high, was built in the 1970s and since then circulates 23,000 liter (!) of water per minute. Especially businessmen appreciate the small courtyard as a retreat. No wonder - the sound of water is quite a bit more pleasant than the murmur on the streets of the big city.
