The rampart lost its military value in the 18th century; in fact, many segments of the rampart were built out with private and state properties, including the triumphal Red Gates and a similar triumphal arch in Triumphalnaya Square (continuously rebuilt in 1721, 1731, 1742, 1762 and 1775). In the same 1775, local authorities entertained the idea of restoring the rampart but were set back by the number of state institutions that had to be demolished. The Fire of Moscow (1812) destroyed these properties, so nothing stood in the way of city development plans. 19th century Rather than rebuild the now useless rampart, according to census records, the city leveled it sometime between 1818–1826. The new free land was developed according to local social status: the upper-class western segment of the Ring acquired central boulevards, flanked by side streets. Present-day streets in this segments are still called Boulevards (Zubovsky Boulevard, etc.). Elsewhere, Garden Ring was set as a 10–20 sazhen (22–43 meters) wide street; unused side territories were allocated to existing homeowners on condition that they plant and maintain gardens at their own expense. These streets usually have a name beginning with Sadovaya–, e.g. Sadovo–Triumphalnaya Street. By 1850, all buildings in this street were completely hidden from view by foliage; the street, indeed, was running through a garden. In south-eastern segment (Tagansky District), the Ring was not as wide, thus Zemlyanoy Val name persisted. Largest square - actually, a combination of two market squares - was created at Red Gates in the north-eastern segment. In the 1830s-1862, Novinsky Boulevard became a popular amusement park with cheap theaters and carousels. In 1841, local entrepreneurs set up a short railroad with a real Mercury tank engine as a pleasure ride for the party crowds. Rails for horsecars (called konka (конка) in Russian) were installed in Moscow since 1872, however, the first lines were built on radial streets; rail construction on Garden Ring peaked in 1891. Likewise, the first electrical tram was launched in 1899, but Garden Ring was electrified in 1907–1910. The circular line traversing the Ring was known as the "B" route (or a "bug" (букашка) in popular language). Gradually, new rental housing of 4, 5, and 6-story buildings replaced the old two-story blocks; Moscow's tallest "skyscraper", an 8-story Art Nouveau Afremov Building, was inaugurated in Sadovaya-Spasskaya Street in 1904.
