Dyce I is an incised stone bearing traditional Pictish symbols including a double disc and Z-rod as well as a Pictish Beast in the act of swimming. The stone is thought to date to about AD 600.
Dyce II is perhaps the most interesting stone. It is a cross slab with a carved Celtic cross decorated with spiral work and knotwork around a central boss. At the base of the cross are Pictish symbols including a double disc with Z-rod, a triple disc, a mirror, and a crescent with V-rod.
On the reverse of the stone is an Ogham inscription which has been transcribed as 'EOTTASSARRHETODDEDDOTS MAQQ ROGODDADD'. The meaning of the inscription is unclear.
What is most interesting on this stone is the combination of traditional Pictish and Christian symbols, but the combination of these with an Ogham inscription is extremely rare. The stone is thought to have been carved shortly after AD 700.
St Fergus Chapel dates to the 13th century, with much later rebuilding. Outside the west doorway is a stone with a hollowed top, perhaps an ancient font.
