We visited Erebuni with our family, unfortunately a part of the museum was closed due to revenovation. The museum is overall a lovely place with lots of interesting artifacts and it was very interesting to be able to visit the remnants of the ancient Erebuni "castle". The staff were helpsome although it was very disappointing that the museum did not invest more into the signs standing outside since they got miscolored. Oh and they do have a sign in front of the castle for blind people.
To sum it up, I definitely recommend this place, very interesting and great history.
