In World War I, after crossing over Albania, where it was annihilated, the Serbian Army recovered after a while and occupied its position at the Macedonian front (Salonika front), which spread across the mountain Kajmakčalan in Маcedonia. On the top of this mountain there was the observation post of the Serbian Army High Command. It is located in the Pioneers Park.
Introduction
After the breakthrough of the Salonika front and a quick break of Serbian Army into Serbia, with the help of French cavalry and the brilliant return of the occupied territories, Serbian Army High Command decided to transport the watchtower from Kajmakčalan to Serbia. The observation post was, by the ox cart, down the traditionally poor roads, taken and reconstructed in the park near the court, that is, in the present Pioneers` Park. It is located in the very centre of Belgrade, opposite the National Assembly, diagonally from the „stone building“, that is, the building in which The Post of Serbia, Теlecom and the National Bank of Serbia are situated. In this monument there are the names of all important generals of Serbian Army, who commanded the Army in the First World War.
History of the Pioneers` Park
The area on which the court complex on Terazije was formed, until 1840s, was one empty and swampy land overgrown in reed. The entire area of today's Pioneers` park, along with Park Aleksandrov, between Kralja Milana Street and Kraljice Natalije Street, was purchased in the late 1830s, by Stojan Simić, one of the most influential people in Serbia, the leader of the Constitutionalist regime and the president of the State council. Simić drained the swamps, filled up and levelled the terrain, and on the odd-numbered side of the present Kralja Milana Street, he erected the house in the period from 1840–1842, which was later on named Stari konak. The repurchase of this edifice with the surrounding garden for the purpose of accommodation of the Prince Aleksandar Karađorđević's court in 1842/43 marked the forming of the first court complex in Belgrade. The integral part of the court complex is the court garden, whose forming is related to the mid-19th century and the erection of the Stari konak, which, at the time of construction, had already been surrounded by some forest trees from the earlier periods.
