A great rent now runs from base to summit of the ruin.

A view of the castle as it was in 1770 is published in Handcock’s “History of Tallaght.”

The fortress is supposed to have been erected in the reign of King John, who granted the manor to Henry de Loundres for his expenses incurred in fortifying Dublin Castle. This grant was confirmed in 1231.

Timon was constituted a prebend of St. Patrick’s in 1247, and it is so still, but without endowment, though in 1306 it was valued at £10 a year.

In an inquisition in 1547 it is described as a “ruinous fortress,” and three years later being a suppressed prebend it was granted to Bartholomew Cusack for twenty-one years. Two or three years later the lands were granted to James Sedgrove, after which they were purchased by Sir Charles Wilmot, from whom they passed to the Loftus family.

Dudley Loftus was in possession of the castle when he died in 1616, and in 1618 the property was confirmed to Sir Adam Loftus.

William Conolly purchased the estate, which still remains in his family.

Some peasantry inhabited the castle towards the close of the eighteenth century.

There was once a village of Timon, of which no trace now remains.
