Old Gorhambury House
Old Gorhambury House located near St Albans, Hertfordshire, England, is a ruined Elizabethan mansion, a leading and early example of the Elizabethan prodigy house. It was built in 1563–68 by Sir Nicholas Bacon, Lord Keeper, and was visited a number of times by Queen Elizabeth. It is a Grade I listed building. 
The house was built partly from bricks taken from the old Abbey buildings at St Albans, then in process of demolition following the Benedictine priory's dissolution some 25 years earlier. It was used as a residence by his youngest son, the polymath (scientist, philosopher, statesman and essayist) Sir Francis Bacon, before being bequeathed by him to his former secretary, Sir Thomas Meautys, who married Anne Bacon, the great-granddaughter of Sir Nicholas.
The estate passed in 1652 to Anne's second husband Sir Harbottle Grimston, Master of the Rolls and Speaker in the Convention Parliament of 1660. The estate is owned by the Grimston family to the present day, having been passed via Harbottle Grimston's son Samuel, who died childless in 1700, to his great-nephew William Luckyn, who in turn became the first Viscount Grimston in 1719.
The house fell into ruin after the construction of New Gorhambury House in the 18th century, but was retained as a feature within landscaped parkland. The surviving remains include a two-storey porch, chapel and clock tower.
The "pondyards", the remains of water garden near the River Ver, were scheduled in 2020 under the Ancient Monuments and Archaeological Areas Act 1979. The feature was laid out in the 17th century for Sir Francis Bacon, possibly adapting preexisting ponds.
The site is maintained by English Heritage and is free to visit.
