Pro-Palestinian protesters shut down the Kelvingrove Art Gallery and Museum in Glasgow on Friday.
The demonstrators staged a sit-in at the building as they called for a ceasefire between Israel and Hamas.
Members of the Arts Workers for Palestine Scotland group gathered at the museum in the afternoon, interrupting the daily organ recital.
The group called for “no more business as usual in the arts”.
In a statement, they said: “Today we took the main hall of Kelvingrove Gallery to protest the silence and hypocrisy of the vast majority of Scotland’s arts and cultural institutions.
“Many more people were outside trying to come in but were refused entry.”
The group accused the majority of Scotland’s arts institutions of being “silent” on the issue.
“We refuse to let the arts, culture and heritage sector continue as if nothing is happening,” they said.
“We call upon all artists, art workers, museum workers, staff, students and cultural audiences to stand with us.”
A Police Scotland spokesperson said: “We are aware of the protest and officers are in attendance.”
A spokesperson for Glasgow Life, which runs the city’s museums, said: “On Police Scotland’s advice, we temporarily closed Kelvingrove Art Gallery and Museum earlier this afternoon while they removed a group of peaceful pro-Palestine supporters.
“The museum has since reopened.”
Gaza officials have said more than 11,000 people have been killed since Israel began its military campaign last month.
According to the Hamas-run health ministry, this includes more than 4,500 children.
Israel began its siege of the territory following Hamas’s attack on the country which killed more than 1,400 people. More than 200 Israelis were also taken hostage.
Israel has rejected calls for a ceasefire but has said it will implement four-hour military pauses to allow humanitarian aid in and civilians to flee.
