There is nothing special to paint here, since in this church is the very Last Supper. Compared to the Vatican Museum, the organization of the tour is simply on top, everything is comfortable, very good guides. Well, it's a little pity for the artist who painted the mural on the opposite wall: no one knows him, although he painted very well and beautifully, and the Last Supper is saved all the time from the moment of its completion.
The church is like a church, nothing special, The Last Supper is kept separately, tickets are booked online a month or earlier before the trip, you will not be able to come and buy, sold out
It is necessary to visit the temple itself, very beautiful, bright, elegant. There is a small, cozy chiostro behind the temple. And for the "Last Supper" you have to come to the opening, at 8 o'clock, and you can take a ticket complete with other museums.
The mural in reality does not look the same as in the images and in the TV shows. Completely different impressions. It breathes the spirit of genius.
An appointment for a visit opens in a few months, you won't get there so easily.
