One of the most prominent sights in the Roman Forum, the basilica of Santi Cosma e Damiano is believed to have been commissioned by Emperor Maxentius to honour his son Valerius Romulus, who died in 309. The building was Christianized and dedicated to Sancti Cosma et Damianus in 527. Throughout the years, many restorations helped keep the structure intact which survived to this day and is one of the more popular tourist attractions, with 6th- and 7th-century mosaics displayed in the basilica.
