Councillors in Anglesey, Wales, have approved plans for a £100 million marina despite local opposition.
Approval was granted earlier for the redevelopment of Holyhead Marina, with new homes, a hotel and a maritime museum now to be built.
A 500-berth marina is also in development at the site.
However, thousands of local residents have signed a petition against the plans, with concerns over the impact on Newry beach among the issues raised.
The proposals were put forward as a joint venture between Stena Line and the Conygar Investment Company.
The partners say as many as 700 jobs could be created as part of the proposals, with local tourism also receiving a boost.
Following the decision, Michael McGrath, area director for Stena Line, told the BBC: “The proposed marina development at Holyhead is not only an important facility for the people of Holyhead and surrounding area but it also represents a significant opportunity to help drive future economic prosperity across the region with the provision of one of the most innovative mixed-use marinas in the UK.”
