Just one day in Milan, which took me on a run in the North West, from Pasteur metro station NE then back down through Parco Lambro, and then a walk from Pasteur into the centre, via Indro Montanelli Park (one of Milan’s many beautiful and spacious parks – seriously, just wander from park to park on a warm day and you’ll be happy). I managed to drag myself from the park before the day ended and headed past the Cathedral (Il Duomo), then West because Cairoli Castello distracted me as I meant to head South. The sightlines are much more Paris (long, clear roads with sights at the end) than London (buildings everywhere with gems hidden behind them).
