UK's Unesco cards

My unesco collection keeps growing. Julia in UK sent me these wonderful cards, all new in my collection.

"New Lanark is a village on the River Clyde in South Lanarkshire, Scotland. It was founded in 1786 by David Dale, who built cotton mills and housing for the mill workers. Dale built the mills there to take advantage of the water power provided by the river. Under the ownership of a partnership that included Dale's son-in-law, Robert Owen, a philanthropist and social reformer, New Lanark became a successful business and an epitome of utopian socialism.
The New Lanark mills operated until 1968. After a period of decline, the New Lanark Conservation Trust (NLCT) was founded in 1975 to prevent demolition of the village. By 2006 most of the buildings have been restored and the village has become a major tourist attraction." - in: wikipedia

"Blenheim Palace is a large and monumental country house situated in Woodstock, Oxfordshire, England. It is the only non-episcopal country house in England to hold the title "palace". The Palace, one of England's largest houses, was built between 1705 and circa 1724. It was recognised as a UNESCO World Heritage Site in 1987.
Its construction was originally intended to be a gift to John Churchill, the 1st Duke of Marlborough from a grateful nation in return for military triumph against the French and Bavarians. Designed in the rare, and short-lived, English baroque style, architectural appreciation of the palace is as divided today as it was in the 1720s. It is unique in its combined usage as a family home, mausoleum and national monument. The palace is also notable as the birthplace and ancestral home of Prime Minister Sir Winston Churchill." - in: wikipedia
