This monument was erected following the Lusitania tragedy. It was commissioned by an international committee which included President Roosevelt and sculpted by Jerome Connor. The Irish language inscription at the foot of the Angel of Peace "Siochain in Ainm Dé" means "Peace in God's Name". The fishermen at the forefront of the monument depict the sheer exhaustion of those who made repeated trips out and back to the site of the sinking of the ship. Their efforts to recover as many survivors as possible and to bring the victims' bodies ashore for burial were acts of great humanity.

At the northern end of Casement Square stands the arched building housing the Cobh Library and Courthouse. This was the Town Hall at the time of the Lusitania sinking and was used as temporary morgue. It was originally constructed as a Market House in 1806 by Mr. Smith Barry of Fota House, whose family crest can be seen on the pediment.
