Nineteen letters of Henry Herbert, Lord Porchester, are now available to researchers. Lord Porchester, born in 1800, was the eldest son of Henry Herbert, 2nd Earl of Carnarvon. He succeeded his father as 3rd Earl of Carnarvon in 1833. The letters, mainly written to his father, describe a journey Porchester took through France and Spain, 1821-1822, with Philip Pusey. The letters record his observations of the places he visited and his impressions of Spanish society. They also provide an interesting commentary on the political situation in Spain following the revolution of 1820.

A catalogue of the letters is available online.
