Another stunning 16th-century architecture in Valletta, the Casa Rocca Piccola provide an insight to lifestyle of Maltese noble families. The palace interior is lavishly designed and is adorned with antique objects. Still housing the de Piro family, underneath the building sits a wartime shelter. It is apparently the second air-raid shelter to have been dug in Malta. It has over 50 rooms inclusive of two large dinning, two libraries, multiple living rooms and a chapel, too. Back when it was built, it was nicknamed as the ‘the house with the garden’, as back then gardens were not permitted at Valletta’s houses. Today a museum it’s fully open to visitors.
