Doctor Arthur Rowe recovered a number of Iron objects from the Tivoli Villa excavations, including the nails, reaping hooks, knives and brackets that are as shown above. He also found a more unusual item shown below,  part of a window grille.

Window grilles were structures that retained small panes of window glass, held by the star shaped clips riveted to the bar, within a wider frame. The grille let in light over a larger opening than could be covered by any single pane of glass that could be made at that time. The presence of a window  indicates the high status of this building. Examples of the type of window glass that would have been used have been excavated locally at Abbey Farm Villa, Minster.
