A stone was unveiled in Newquay in memory of the three holidaymakers who died in the Penhallow Hotel fire in August 2007.
A service was held on the seafront to unveil the plaque, which was mounted on a slab of granite and placed on a green opposite where the Penhallow Hotel stood.
As well as remembering those who died, the stone also paid tribute to those who helped in the rescue operation.
Peter Hughes (43), his mother Monica (86) and Joan Harper (80), who were all visiting from Staffordshire, died in the fire.
Newquay town Councillor John Fitter said: “Three people lost their lives and that is a tragic event and we wanted to mark it. It was a united effort and volunteers came and serviced the community that night. That’s what it’s all about, a society coming together.”
The memorial stone is mounted onto a piece of granite from Newquay’s headland.
Sue Harper, whose aunt, Joan Harper, died said: “Things don’t ease. The grief carries on, and although it’s nice to come down and thank people, it’s not been easy.”
