The phenomenal organ in St Bavo Cathedral in Haarlem, The Netherlands. It is a Muller, built in 1738 and was played by both Handel and Mozart. It is a triumph of religious and apparently governmental extravaganza, owing to the coat of arms on the top.
Organ of the Sint-Bavokerk, Haarlem. It was built by Christian Müller and Jan van Logteren, from Amsterdam, between 1735 and upon completion it was the largest organ in the world with 60 voices and pedal-towers.
