Rahmi M. Koç Museum

Museum · HasköyIstanbul,Türkiye

An eighteenth-century anchor foundry on the Golden Horn packed with engines, cars, aircraft and a retired Istanbul ferry moored at the quay.

The Rahmi M. Koç Museum fills an eighteenth-century anchor foundry on the Golden Horn, and it is a museum you climb into rather than look at. The thick-walled stone halls hold steam engines, vintage cars, model railways, aircraft and rooms recreating old workshops and ship bridges. Children turn cranks and press buttons; adults linger over a restored steam locomotive or a lavish railway saloon carriage. A second wing occupies a nineteenth-century dockyard across the lane, and the collection spills outdoors onto the quay. Outside, full-size machines stand parked against the water, from a Douglas DC-3 to old boats and rail cars, and the retired ferry Fenerbahçe is moored at the quay. The Lengerhane, as the foundry was called, once forged chains and anchors for the Ottoman fleet. Turkey's first major museum of transport, industry and communication was assembled from one industrialist's private collection and opened in the 1990s. A period French café keeps one corner of the site.

Worth knowing

Good to know

Come ready to touch — Unlike most museums in the city, much here is meant to be handled and boarded; the interactive galleries reward the curious, not the cautious.
It spreads across both sides of the lane — Many first-timers tour one building and leave, never crossing to the dockyard wing over the road. Half the collection waits on the other side.
The café is itself an exhibit — The belle-époque French café on the grounds is a preserved period piece, worth a coffee even if you skip a full meal.
Look for the foundry's bones — Between the polished machines, notice the thick stone walls and old vaulting; the building predates almost everything it now displays.

Things to do

1
Walk the quay along the old ferry
Follow the waterfront to the Fenerbahçe, the broad white ferry tied up along the museum quay. Read her lines from the bow back: the open promenade decks built for commuters, the tall funnel, the wooden benches that faced the sea. She ran the Princes' Islands and Kadıköy routes for over half a century.
2
Work the hands-on machines
Head into the foundry hall and use the interactive exhibits rather than reading past them. Turn the cranks, pull the levers, set a model railway or a steam-engine cutaway in motion. Watch how a mechanism you can touch explains itself better than any label. Best done slowly, letting children lead.
3
Stand under the DC-3's wing
Out on the quay, walk to the Douglas DC-3 and stand directly beneath the wing, close enough to read the lines of rivets. Then turn and look across the water: the old-city skyline rises on the far shore of the Golden Horn, with the aircraft's tail set against it.
