Rahmi M. Koç Museum

The Rahmi M. Koç Museum in Ankara is part of the same foundation as the larger Istanbul branch, housed in a restored 19th-century gas plant complex in the Altındağ district near the Çubuk Stream. The museum presents an extensive collection of transport, industrial, and communications artefacts spanning roughly two centuries of technological development, with a particular emphasis on items that were manufactured in or have a connection to Turkey. The indoor galleries occupy several former industrial halls and display steam locomotives, early diesel engines, vintage automobiles ranging from 1900s carriages to mid-20th-century Turkish-manufactured vehicles, motorcycles, aircraft engines, and a comprehensive collection of scientific and medical instruments. A full-size submarine — the TCG Uluçalireis, a WWII-era vessel acquired by Turkey — is the centrepiece of the outdoor area, accessible for internal tours. Additional outdoor exhibits include a steam engine on track, vintage military vehicles, and a light aircraft. The communications gallery traces the history of telegraphy, telephony, and early computing with original equipment. A model trains section appeals strongly to younger visitors. The café and restaurant on site are well-regarded and set within the restored industrial architecture of the former plant. The museum shop carries transport-themed models and books. Admission is 150 TRY. The site is less well-known to international tourists than its Istanbul counterpart, meaning queues are rare even on weekends. A full visit takes 2–3 hours.
