Argyll and Bute Council invested £200,000 to restore the Category A-listed Avenue Screen.
Scaffolding, which was first erected at the site in January, has been removed and the finishing touches have been made to the work, which saw the Avenue Screen's cement render removed and replaced with traditional lime render. Work was also carried out on the famous archway's gates.
Weather-proofing was also completed as part of the council's drive to protect Inveraray's architectural appearance following previous major repair and conservation works to a string of buildings in the town.
Policy Lead for Economic Growth, Councillor Alastair Redman, said: "The Avenue Screen is such a prominent part of Inveraray's landscape, and we are pleased that this work to both enhance and protect the structure has now been completed.
"It's one of the things that first catches your eye when you approach Inveraray, and we hope that residents and visitors alike will appreciate the difference that is very clear to see."
