Prince August built a Catholic church in Coburg. It was consecrated in 1860 and was named St. Augustin. He was later buried in the crypt below this church, as were his wife, his three sons, his daughter-in-law Leopoldina and her four sons.
In 1885, the Austrian sculptor Viktor Tilgner was commissioned to create a memorial for the late Prince August. The sculpture still stands on private land in Ebenthal owned by the Saxe-Coburg ducal family. The base of the sculpture contains a Latin inscription and a text in French: Auguste Louis Victor Duc de Saxe Prince de Saxe Cobourg Gotha. À mon mari bien-aimé. 1843 - 1881. Clémentine. ("August Louis Victor, Duke of Saxony, Prince of Saxe-Coburg-Gotha. To my beloved husband." — 1843 is not the year August was born (he was born in 1818), but rather the year he married Clémentine).
Marie Luise Franziska Amalie (b. Coburg, 23 October 1848 - d. Schloß Biederstein, 6 May 1894), married on 20 September 1875 to Maximilian Emanuel, Duke in Bavaria.
Ferdinand Maximilian Karl Leopold Maria (b. Vienna, 26 February 1861 - d. Coburg, 10 September 1948), installed as Prince of Bulgaria on 7 July 1887; raised to Czar of Bulgaria on 22 September [O.S. 5 October] 1908.
On 2 May 1881, Emperor Franz Joseph I of Austria bestowed upon August and his descendants the style of Hoheit ("Highness"), a higher style in Germany than Durchlaucht ("Serene Highness"), which Ernestine princes were usually entitled to. The reason for the grant was that eight days later Princess Stéphanie of Belgium (younger sister of August's daughter-in-law Louise) was to marry Franz Joseph's son Crown Prince Rudolf; Franz Joseph considered it appropriate that his son's in-laws have a higher rank at the Austrian court.[citation needed]
