Works are ongoing to set up a concrete wall separating the Grand Serail from Riad al-Solh Square in a bid to deter protesters.
Meanwhile, citizens used the wall as a platform to express their opinions by writing various slogans.
Workers cleared away the debris and razor wire barricades as security forces and army members patrolled the road in central Beirut, which houses the parliament building as well as the prime minister's residence and historical monuments.
Anger at the unity cabinet grouping Lebanon's fractious politicians has come to a head over its failure to resolve a crisis over garbage disposal.
Prime Minister Tammam Salam's cabinet has been hamstrung by political and sectarian rivalries that have been exacerbated by wider crises in the Middle East, including the war in neighboring Syria.
