They have literally TONS of castles all over the place . I had to have seen at least 10 just driving around . Coupled with the fact that tourism is very very small in Wales they do n't have visitor centers and charge you to see them . You just drive up and walk in .

Question: Why do they have so much of what they have ?
Answer: None of the above choices .The tourism love their place a great amount .The castles must 've all been built in the past .The huge amount of tourism must be there to see the castles .
