North Stack is a redundant Fog Signal Station of local historic significance, which has been converted into a bird watching observatory.The house and buildings date back 200 years. It faces SW and looks
across the magnificent Gogarth Bay towards South Stack Lighthouse (now open to the public) and the RSPB Nature Reserve.
