ENGLISH Heritage is hoping to reverse the decline in the number of tourists to a North Yorkshire castle, by building a visitor centre and new entrance.

This week, the North York Moors National Park Authority will be recommended to approve the scheme at Helmsley Castle.

English Nature said the plans represented the first phase of a new project for the historic castle.

A spokesman said the work involved improvements to other parts of the site in the market town, including a new exhibition area within the Tudor Mansion, as well as environmental facelifts.

"We aim to increase the attractiveness of the castle as a tourist attraction," said English Heritage.

The scheme will also provide employment, improve access to the castle and extend its opening season. Educational outreach projects will also be developed.

Val Dilcock, the park authority's head of planning, said the castle was of national archaeological importance and an evaluation of the site was needed.

She warned that some trade may be lost to businesses in Helmsley with the opening of a visitor centre shop and cafe, but said: "It is anticipated that any loss of trade would be modest, with greater benefits arising from the potential increase in the number of visitors attracted by the enhanced visitor experience at the castle."

The complex would be built near the northern end of the castle grounds close to the Cleveland Way footpath.
