Blaise Castle is a Iron Age hillfort located near Henbury in Gloucestershire, England, whose defensive earthworks represent an important example of prehistoric fortification in the region. The site retains substantial archaeological evidence of Iron Age occupation, including the characteristic banks and ditches that once enclosed the settlement. Later Roman and medieval activity at the location demonstrates continued use of the strategically significant hilltop, whilst the post-medieval period saw the transformation of part of the site into a designed garden landscape that reflects eighteenth-century picturesque aesthetics. The combination of prehistoric defensive works with subsequent layers of occupation and landscape modification makes Blaise Castle a complex palimpsest of settlement and land use spanning more than two millennia.
