The museum contained some interesting information about the Viking ages along with some replicas of the Viking ships they have found in the harbour nearby . Overall , however , it was a pretty boring museum that just seemed rather empty . I would not recommend a separate trip to go and see it . After leaving someone disappointed from the museum , we trekked back up the hill ( with a couple of rest / photo stops ) towards town .

Options are: 1. there have not actually been any authentic ones found; 2. The authentic ones are too fragile to be put on display; 3. None of the above choices .; 4. Someone made replicas and was proud of them;
Q: why might the viking ships in the museum have been replicas ?
2.
