Rizhskoye

[2] In the late 17th century Kalthof, Lawsken, and Spittelhof were possessed by Johann von Hille, commandant of Fort Friedrichsburg.

[3] The 1,100 morgen Devau Revuefeld just east of Kalthof was the oldest large training ground of the Prussian Army, with exercises held annually since 1717.

[5] In 1893 Kalthof contained barracks for two pioneer battalions of the Prussian I Corps,[6] the Pionier-Bataillon Fürst Radziwill (Ostpreußisches) Nr.

In 1905 the estate's final owner, Berthold Kleist (1848-1932), sold Kalthof to Königsberg, allowing it to be incorporated into the city.

[7] Kalthof was connected to central Königsberg by the street Labiauer Straße (formerly Königsallee), which met Königstraße at King's Gate.
