In 1856, the ramparts of the :lv:Rīgas citadele|Riga Fortress were demolished, replacing the 'Sand Bastion' with the name of Basteiberg . In 1879, the Riga Gardens Directorate was established and the 27-year-old Georg Kuphaldt was officially appointed Director of the Riga Gardens. His first project was the reconstruction of the greenery of Bastejkalns. The creation of the Basteiberganlagen plantation of the Bastion Hill lasted from 1859 to 1887. In 1860, a wooden pavilion was erected and replaced in 1887 with the first Bastion Hill café. The waterfall cascade built from :lv:Saulkalne|Saulkalne's dolomite into the mountain was built in 1898. It has survived to the present day, but no longer with the less sophisticated underwater lighting that was still operational at the beginning of the last century. Around 1893, a pseudo-swan-style swan cottage, work of Riga's architect Heinrich Scheel, was placed on pontoons along the Bastejkalns Canal - usually pulled ashore in the winter months, where it is still today. Swans donated by "Riga Bird Breeding Society". In 1883, at the foot of the Bastion Hill, a 23-meter-long wooden bridge was erected over the canal, which was replaced in 1893 by masonry. Then a bridge was built to connect the Old Town with what is now Rainis Boulevard. In 1951, according to the architect Jānis Ginters project, Bastejkalns built support walls, which used parts of the buildings of Riga destroyed by World War II. The Bastion Hill greenery was restored with various sculptures in 1968. The square of this public park was used until 1856 as part of the eastern fortifications and consisted in this area of earthen ramparts, covered trenches, bastions and moats. This fortress section was assigned to the commander of the 'Powder Tower'. In the following years, the open ground was reshaped by considerable landfills and the :de:Stadtkanal |city canal and connected to the eastern suburb by new bridges. At the suggestion of the architects Johann Felsko and Otto Dietze, a green area of parks and gardens as well as a broad boulevard were created here. For a large part of the facilities, the landscape architectGeorg Friedrich Ferdinand Kuphaldt was acquired as a planner. A landmark and enrichment of the plant are the 1898 designed as :de:Wasserkunst|Wasserkunst waterfall. To those the city canal in the area of the park spanning bridges belongs the 1900 built :de:Timmbrücke|Timmbrücke. The park has been expanded to include more monuments and facilities, including the Freedom Monument and the two memorial stones for the victims of Riga citizens and security forces who died in January 1991 in an OMON deployment. As early as 1929, the construction of the :de:Blaumanis-Denkmal|Blaumanis Monument was completed. As part of a reorganization from 1968, the sculpture :de:Friedenstanz|Peace Dance was erected in 1970. In 2006, Elizabeth II and Vaira Vīķe-Freiberga unveiled :de:Armitstead-Denkmal|monument to Riga Mayor George Armitstead. In 2007, the unveiling of the :de:Vīgners-Denkmal|Vīgners Monument took place.
