Nice fortress with a high tower from where you can see the Estonian-Russian border. The entrance fee is really cheap (e.g. Only 1,50 euros for Students) and there is an interesting exhibition about the history of the castle and of Narwa and its river as well. There is a panoramic view at the top of the tower, but only through little windows.
Awesome time here sight seeing
Must see in Narva
Impressive building! Take time to visit the tower and to take a look at the town Narva and the Ivangorod castle on the other side of the river.
That is a unique place to visit
Ancient castle, which official name is Hermann Castle, built in 13th century, now is the town museum, where you can find different historical exhibitions, and try yourself in different handicrafts and just a stunning place. Russian castle from pretty much the same age is just across the river. which makes this place unique and very special. You have to visit it, if you are in Estonia!
