You can walk around it within an hour. Basically, there are only remnants of walls of the fortress with some descriptions. We thought an excursion would be great. The museum is quite small, takes another half hour
The ruins of a great Erebuni fortress, very sad that it's not reconstructed. Also there's a nice museum nearby and the landscape from the wall is amazing - you can see the city and mountains from there. Definitely that one of the places in Yerevan to visit.
An extremely interesting historical place! However, the state and the way this country's treasure is kept disappointed! The museum is interesting and well maintained, but it could be better on the territory of the fortress itself! Commemorative plaques, photographs, signs, etc. have faded, are not updated, it is not possible to read anything!
