Rahmi Koc Museum opened at 1994. It's near the Golden Horn. The Rahmi Koc Museum is the first major museum in Turkey.
I went to Rahmi Koc Museum with my school two days ago. We saw old cars, old ships, toys and many interesting things.
There are three main sections. The museum in 27 thousand square meters of area.
A planetarium is in the museum. Planetariums are systems designed for teaching about astronomy.
Absolutely must visit.
