Brooch is cast in silver, gilt, and gold, silver and amber, and decorated with interlaced animal bodies in gold filigree. In its centre, a cross and a golden Glory represent the Risen Christ.

Nowadays, it is considered one of the most significant items of Celtic art, and is housed in the Royal Museum of Scotland, Edinburgh. Medieval Several buildings in the area date back to medieval times. Law Castle, situated at the foot of Law Hill, was built in the 15th century for King James III's sister Mary. The castle is a simple rectangular structure with a sloping roof and several large chimneys protruding at each side. In recent years, Law Castle has been substantially restored and refurbished and it now letted for functions and as a holiday home. Portencross Castle, thought to date from the 14th century, is situated right next to the sea at Portencross harbour. It is L-shaped and four storeys high, with a barrel-vaulted ceiling. The castle was roofless for many years due to storm damage. A campaign to save Portencross Castle from private ownership received national publicity in July 2004 when it was featured on the BBC's Restoration television programme. The title for the castle and grounds was given to the group "Friends of Portencross Castle" on 22 December 2005. Crosbie Castle (also known as Crosbie Towers) lies to the north east on the outskirts of West Kilbride. It was largely rebuilt from a tower demolished in the 17th century which was the home of Sir Ranald Craufurd (uncle of William Wallace) in the 13th century, and it is said that Wallace himself spent some time at Crosbie. Currently the castle lies at the centre of a caravan park also called Crosbie Towers. Having lain empty for a number of years due to internal fire damage, part of the building was demolished in early 2007 after heavy storms damaged the external walls of the castle. Although the building is a Category-B listed building, permission was not sought before demolition.
