The sites of Aber Camddwr II and Parc Maen are separated by some distance, lie at different heights and the radiocarbon dates indicate that several centuries may have divided their construction. However, they are published together as it is considered that their similarities complement each other. At both sites the erection of standing stones, the setting up of timber posts and the deposition of charcoal in pits took place during or after the construction of a cairn. The cairn at Parc Maen was built at the beginning of the second millennium BC, that at Aber Camddwr in the middle of the same millennium. At both sites the cairns may have covered primary inhumations, with circumstantial evidence for later cremations at Parc Maen, although the principal secondary function of both sites appears to have been ceremonial rather than sepulchral.

An analysis of the standing structure of a large early-Renaissance style mansion added to a late medieval hall-house. This report contains a description of the excavations and historical notes on the house.

A review of the range of the marks used together with speculation on their use in the medieval period and an attempt to sequence the various stages of construction using these marks.
