前總理伯蒂-埃亨（Bertie Ahern）在儀式上發表了講話，他將特林布爾勳爵描述為一個 "熱情而堅定的和平締造者"。
A portrait of Nobel peace-prize winner Lord Trimble has been unveiled at Queen's University in Belfast where he was once a student.
Before entering full-time politics, the former Ulster Unionist leader also lectured in law at the university.
The portrait by artist Colin Davidson will be permanently displayed in Queen's Great Hall as a tribute to him.
At a ceremony at Riddel Hall, the portrait was unveiled in front of Lord Trimble and his family.
Lord Trimble was awarded the Nobel prize, along with then SDLP leader John Hume, for their part in the Good Friday Agreement in 1998.
Video messages were sent from former US President Bill Clinton, former Prime Minister Tony Blair and current Prime Minister Boris Johnson.
A speech was made at the ceremony by former Taoiseach Bertie Ahern, who described Lord Trimble as a "passionate and determined peacemaker".
The Northern Ireland Office Minister Conor Burns was also there. He told Lord Trimble that "courage has defined your career".
After the Good Friday Agreement, he became the first ever first minister at Stormont.
One of those against it was Dame Arlene Foster, who was at the ceremony along with a number of other unionist politicians including Robin Swann, Mike Nesbitt, Steve Aiken, Jim Rodgers and Danny Kennedy.
The former SDLP leader Mark Durkan also attended the ceremony along with a number of civil servants who used to work at Stormont.
The vice-chancellor of Queen's, Prof Ian Greer said: "Lord Trimble has a longstanding link to the university, having lectured in law for 21 years.
An annual lecture in his honour will be held. The first was delivered on Monday evening by Lord Paul Bew, a professor emeritus in politics at Queen's.
