Mellieħa World War II Shelters: 0.5km long, these air-raid tunnels are a sobering experience. There are a couple of displays, gas masks, digging tools and so on, and some rooms have been restored to their wartime appearance, but you could probably do without the spooky mannequins.
Tunnara Museum (Westreme Battery): A Knights Hospitaller-era blockhouse turned tuna storehouse is an apt setting for Mellieħa’s quirky tuna fishing museum.
