The UK's only gallery devoted to modern Italian art, Balla, Boccioni and the Futurists, tucked into a Georgian house on a leafy Canonbury square. Small, serene, with a lovely café and garden almost nobody knows about.
Open Wed, Sun (closed Mon/Tue and between shows). Check it's open before trekking to Canonbury.
If Italian Futurism isn't your thing, it's a quick visit, but the café and garden make it a worthwhile slow stop.
