North of old Jeżyce is Sołacz, an area with many large houses and the green areas of Sołacz Park. Smaller neighbourhoods in this area include Niestachów, Urbanowo, Wierzbak (a stream called Wierzbak runs underground here, beneath the street "Nad Wierzbakiem" – "Over the Wierzbak" – to meet the Bogdanka), and Bonin. North of Sołacz is the area known as Winiary. Historically the villages of Winiary were in the area of today's "Cytadela" and southern Winogrady in Stare Miasto district (the names Winiary and Winogrady derive from the vine cultivation that formerly occurred there) – in the 1830s, because of the Prussian authorities' plans to build fortifications there, the inhabitants were moved to the area now called Winiary.
