* We invite you to take a trip around the City of Passageways. The St. Petersburg Passageways are not exactly a tourist story and are very ambiguous. Someone likes walking around the yards endlessly and people "get sick" of the yards, someone does not really, but there is absolutely no one indifferent. In order for your personal St. Petersburg puzzle to take shape, it is worth looking into the courtyards at least once, at least with one eye ... Usually tourists are afraid to look into the St. Petersburg gateways and front doors. They seem dark and unfriendly to them. And in vain, because there is a whole world hiding behind them. The world of passageways. Inside, another city is hiding behind the chic facades. The real Petersburg, as it is, without embellishment and gloss. Getting into this world is not so easy, arches and front doors are often closed. For such a trip, you will definitely need a reliable guide.
