An architect's design of the new centre

Visitor numbers to the existing William Wordsworth museum at Dove Cottage, in the heart of the Lake District, have been about 20% lower than normal.

Usually about 75,000 people visit Dove Cottage, the 18th Century poet's home, each year.

Since it was founded in 1891, the trust has developed a museum, archive, store, library and shop.

The new building will mean greatly-improved conditions for the long-term conservation and care of "Wordsworthiana".

The collection features about 50,000 items, including the letters and working papers of Wordsworth and other poets.

Watercolours and paintings by many Romantic artists will also be on display.

The grant will give better access to Wordsworth's manuscripts for researchers from all over the world.

Anthea Case, Director of the Heritage Lottery Fund, said: "Wordworth is one of Britain's most well-loved poets and it is fitting that a special centre should be created to honour his work.

"This facility, once built, will increase employment and understanding of Wordworth's life and work, as well as boosting Cumbria's tourist industry.

"We always look for a 'double-dividend' funding benefit and this is a prime example.

"The award will increase visitor access to the project as well as helping to regenerate an area which has suffered considerable hardship over the past year."
