The Estadio Nacional - the scene of Billy McNeill and Celtic's greatest triumph.
It was at this historic Portuguese stadium in 1967 that the Lisbon Lions were born, mauling a famous Inter Milan side to become the first British team ever to lift the European Cup.
McNeill holding the famous old trophy aloft is perhaps the most iconic image in Celtic's storied 131 years.
And now, following the legendary defender's passing aged 79, a simple, touching tribute has been left to the great man at the site of his finest hour.
An unknown fan laid flowers, a Celtic shirt and a short note at the gates of the stadium in honour of the man nicknamed Cesar.
The current Hoops team did the club's greatest ever skipper proud on Saturday with a 1-0 win over that Kilmarnock that takes them to within a point of eight-in-a-row.
