During an instrumental interlude, the music creates a thunder storm to indicate the passage of time. Almaviva and Figaro climb up a ladder to the balcony and enter Rosina's room through a window. Rosina accuses Almaviva, whom she believes to be Lindoro, of betraying her. Almaviva reveals his identity and the two reconcile. While Almaviva and Rosina are enraptured by one another, Figaro keeps urging them to leave. Two people are heard approaching the front door. They are Basilio and the notary. The Count, Rosina, and Figaro attempt to leave by way of the ladder, but discover it has been removed. Using bribes and threats, Almaviva coerces the notary into marrying him to Rosina, with Basilio and Figaro as the legally required witnesses. Bartolo barges in, accompanied by the Officer and the men of the watch, but too late; the marriage is already complete. The befuddled Bartolo is pacified by being allowed to retain Rosina's dowry. The opera concludes with an anthem to love ("Amor e fede eterna, si vegga in noi regnar!"; "May love and faith eternally be seen to reign in us").
