Over £1.3m from the Heritage Lottery Fund will help ensure the Gower Peninsula remains an area of outstanding beauty.
The money will pay for a programme of activities to protect the area that is currently at risk from pressures created by tourism.
Famous for its limestone cliffs, secluded bays, sand dunes and saltwater marshes, the Gower is visited by thousands of people every year.
The Gower is home to historic sites such as the Upper Palaeolithic caves, a Bronze Age funerary and Iron Age hill forts. Swansea council will work with organisations including the National Trust and the Wildlife Trust to conserve these sites.
Llancaiach Fawr employees say a £943,200 grant awarded to the manor will be used to help tell 'a complete story of the all the people who lived and worked there' and make the site accessible for all visitors.
With the support of the Heritage Lottery Fund, not only will we will be able to show the difference between the living conditions of the servants, as well as the gentry owners, for the first time, but we will also be able to open up the vast majority of the building to visitors with mobility difficulties who have formerly only been able to access the ground floor.
– Diane Walker, General Manager of Llancaiach Fawr Manor
Llancaiach Fawr Manor has been awarded a £943,200 grant, which will see its hidden attic - a former servants' quarters - opened up to the public for the very first time.
The Grade I listed Tudor mansion in Nelson, near Caerphilly, is restored and furnished as it would have been in 1645. The money will be used to improve and conserve the attraction, and also provide better access for wheelchair users.
Cllr Ken James at Caerphilly County Borough Council said the Heritage Lottery funding 'would help transform the way the past is presented to a modern audience'.
