The printmaker, artist, writer and conservationist became something of an unlikely personality on the Irish version of the reality television show.
She died unexpectedly in April of this year at the age of 73.
Siobhán and her husband Dr Pat Wallace, a former director of the National Museum of Ireland, were regulars Gogglebox since 2017.
They spent several years reacting to some of the biggest television moments, filmed every Saturday from their home in Ballsbridge for the Virgin Media show.
“It was Siobhán’s idea and they loved the character of a ‘quirky’ D4 couple,” said Pat.
Ms Cuffe Wallace had a passion for Irish heritage, learning the language later in life and restoring a 15th-century Gaelic tower house in Co Clare. She was also the sister of MEP Ciarán Cuffe.
Dublin City Council, in collaboration with local businesses and the Pembroke Road Residents’ Association, unveiled the benches yesterday.
“Urban economies have a reputation for being fast-moving and driven by a desire to speed everything up,” said Lord Mayor of Dublin, James Geoghegan.
“When planners talk about infrastructure, they focus on transporting people and cutting journey times.
“It is nice to step every now and again into the more ethereal and rewarding spaces, occupied by those who stop and sit, to watch, to meditate, to observe.
“Dublin is a city of writers and poets, of those who observe and compose music, and who converse in our famous lyrical language. Siobhán understood this better than most,” he added.
Alongside the Lord Mayor, Siobhán’s husband Pat, her brother Ciarán Cuffe, and Brian Hanney of Dublin City Council also spoke, celebrating the unveiling of the benches as a tribute to their late friend, sister and wife.
