The gardens of Lowther Castle will be open once more to the public on Good Friday.
As part of a £9m restoration project 121 acres were rescued from abandonment and will be seen by visitors for the first time in 70 years.
By July the Castle ruins, a shop, museum and gallery will open.
Tourism in Eden like many parts of Cumbria is big business for the local economy.
It brings in 4 million visitors and £217m each year.
Eden tourist board hopes the new attraction will boost visitor numbers in the area.
