This paper examines the character and significance of a cellared structure discovered during recent excava tions on the site of a later Anglo-Saxon settlement at Bishopstone, East Sussex. The structure in question formed a focal element within an estate centre complex administered by the Bishops of Selsey from c. AD 800, otherwise surviving in the celebrated pre-Conquest fabric of St Andrew's parish church. The excavated footprint of this cellared structure is examined in detail and conjectural reconstructions are advanced on the basis of comparative evidence garnered from historical and archaeological sources. The collective weight of evidence points towards a tower, pos sibly free-standing, with integrated storage/cellarage accommodated within a substantial, 2 mdeep subterranean chamber. This could represent a timber counterpart to excavated and extant masonry towers with thegnly/episcopal associations. The afterlife of this structure is also considered in detail on the grounds that it provides one of the most compelling cases yet identified of an act of ritual closure on a Late Anglo-Saxon settlement. Alongside being dismantled and infil led in a single, short-lived episode, the abandonment of the tower was marked by the careful and deliberate placement of a closure deposit in the form of a smith's hoard containing iron tools, agri cultural equipment and lock furniture. One of the few such caches to be excavated under controlled scientific conditions, it is argued that the contents were deliberately selected to make a symbolic statement, perhaps evoking the functions of a well-run estate centre.
