The development of the former Prague Suburb east of Nepomucká Avenue did not reach Homolka Hill until the 1930s. However, the beginnings of smaller neighbourhoods with the patriotic names Vyšehrad and Petřín already appeared near the railway from Cheb to Vienna immediately beyond the city limits before the First World War. At about the same time, the complex of the Czech Pilsner Brewery (later known as Světovar) was built within the city boundaries. The regular Petřín blocks soon reached Koterovská Street opposite the brewery. Yet, both Petřín and Vyšehrad remained islands detached from the “body” of the suburb until the 1950s, when the construction of the Slovany housing estate began. This did not change with the construction of a new tram depot on the axis of Slovanská alej near the brewery in the first half of the 1940s.
Besides the above-mentioned industrial and technical objects, the trail also presents the Petřín Sokol Hall and a cross-section of period residential housing development. It includes single-family houses and sets of rather modest terraced houses in Petřín, a functionalist complex of three apartment buildings for employees of the City of Pilsen Electrical Company, a block of single-family houses and semi-detached houses on the gentle slope of Homolka as well as the grand house of Jan Kokoška, owner of a stonework operation and granite quarries.
