An inflatable walk-through palace of light and colour has been set up in St George’s Square, Valletta, for Luminarja, a project by Architects of Air, that runs until Sunday, when World Children’s Day is celebrated. The palace is one of the highlights of Żigużajg, the week-long programme of performing arts for children organised by the Office of the Prime Minister with St James Cavalier. On weekdays it is on from 10 a.m. to 1 p.m. and 4 and 7 p.m. and from 10 a.m. to 7 p.m. on Saturday and Sunday.
