Vintage lovers!
The Planetarium of Milan, Civico Planetario "Ulrico Hoepli", is a building located at the entrance of Giardini di Porta Venezia. It's a beautiful structure designed by Piero Portaluppi and commissioned by the Italian-Swiss publisher Ulrico Hoepli.
Also the interior design is beautiful, there you can find a planetarium which projects and represents the image of the stars and their movements in the sky.
The Planetarium also has a library which is a section of the Museum of Natural History, near by.
They also organize educational activity concerning astronomy as talks, events and even concerts.
I consider e/c natural wine shop a hidden treasure in Milan. Inside a building with an "Emergency" (that is actually an ONG) plaque outside, the first thing one might think is that is a hospital. Once passing the wall, there's a cute internal square, with Basilica di Sant'Eustorgio view. You can sit both inside or outside, which a strongly recommend for spring and summer days. A nice place for just passing by to grab a bottle of wine and drink it at home, having a glass of wine (they have many options) or enjoying a relaxed evening.
To really reach/understand a city you must live there or, at least, acting like you do. Nothing makes you feel more like a Milanese D.O.C. than stopping by Frida's on a Sunday morning to buy some flowers. Located in Brera this tiny shop has an extraordinary colour palette of flowers and plants. After that we just take a walk in the neighbourhood holding our bunch of Brassica Oleracea and our day is made.
