Across the road of the main entrance and the major exhibits is a restored old building. It was the first building of the museum. Called the Lengerhane it is an old Ottoman anchor house, founded under Sultan Ahmet III (1703-1730) on the basis of a Byzantine building from the 12th century.

It now mainly houses lots and lots of scale models of the type of things one finds in the main exhibits: steam engines, machinery, trains, trams, boats, as well as many small objects like electrical appliances. There is also a mock-up of the bridge and some rooms in a steamer. And a plane,. And so forth: a museum by itself, but much, much more quiet and more "educational", closer to a science museum. I only went there once, but hope to return.
