Over the years the Apponyis built or acquired numerous properties in the Kingdom of Hungary and in Vienna. At the peak they had around 30 properties to their name over the empire. Several of these still stand.
Appony (today Oponice, Slovakia) The Apponyi fortress on a hill above the village probably already existed in the time of
Great Moravia and was acquired by the Apponyis in 1392. In 1645 it was badly damaged by fire and was finally destroyed by the Habsburg army in 1708 after it had been used by
Kuruc rebels during
Rákóczi's War of Independence. It was reconstructed into its current form sometime after 1817 by Count György Apponyi (1780–1849), eldest son of Antal György. It then went to his son György Apponyi who died in the castle in 1899. Albert Apponyi lost property of the castle following the Treaty of Trianon.
Jablánc (today Jablonica, Slovakia) The manor in
Jabloncza, inherited by the family in 1772, was remodeled by József Apponyi around the time of his elevation as Count in 1808, possibly to better reflect his new higher status. It was again remodeled in the late 19th century by Count Antal Apponyi (1852–1920), who inherited it from József's son Rezső Apponyi.
Hőgyész (Hungary) The
Hőgyész domain in
Tolna County was acquired in 1722 by
Count Claude Florimond de Mercy, and purchased by György Apponyi (son of Lázár) in 1772. It was rebuilt in the late 18th century by György's son, Count Antal György Apponyi, who spent much of the rest of his life there.
Lengyel (Hungary) The
Swabian village of
Lengyel ("Polish" in Hungarian) in
Tolna County was purchased by Count Antal György Apponyi in 1799. The castle was built by Antal György's third son József in 1824–1829 and extensively remodeled from 1878 by
Sándor Apponyi. It suffered fire damage in 1905. After Sándor's passing away, his widow Countess Alexandra
Esterházy donated the castle in 1926 to the
Hungarian National Museum but kept the privilege of living there until her death in 1930. During
World War II it was used by Hungary's
National Cartography Office, then became a Russian
military hospital from January to March 1945, and later that year an internment camp for
displaced Germans. It has been an agricultural school since 1946.
Urban properties The Apponyis inhabited various properties in the capitals cities of Vienna, Pressburg (Pozsony, today's Bratislava) and Budapest, many of which were rented. The
Apponyi Palace in Bratislava, built by Count György Apponyi (1736–1782), was sold in 1865 to the municipality of Pressburg. The
Palais Apponyi in Vienna was built in 1880 for Marguerite and Lajos Apponyi. Albert Apponyi lived in an old house on Castle Hill in Budapest, now Táncsics Mihály utca 17, where a plaque honors his memory and that of his son György.
Other • The medieval castle in Cseklész (, near
Bernolákovo, Slovakia) was held by the family before they switched it for the Appony domain in 1392. • Balázs Apponyi also owned a castle in Pereszlény (now
Preseľany, Slovakia), now destroyed. • The Appony line of the family owned the village castle in
Kovarce () (today in Slovakia) from 1876 to 1926. • A roadside mansion in
Bátaapáti in
Tolna County (Hungary), was built by the Apponyis in the 1840s and renovated in 2005–2006. • A manor in
Medina (Tolna County), built in 1840 and purchased by the Apponyis in 1850, has been renovated as a hotel branded
Apponyi Kiskastély (Little Castle of Apponyi). • A manor in
Pálfa (Tolna County) was built in 1924–1928 by Géza Apponyi (1853–1927) and his son Károly (1878–1959), who died there. Géza was the son of Károly Apponyi, eldest son of Count Antal Apponyi's eldest son György (of the Malinovo line). The domain of Pálfa was apparently acquired by the family in 1772 together with Hőgyész. The building now serves as a home for disabled people. • There are many, many other properties that the Apponyi family supposedly owned during their time within the Kingdom but also all over Europe Aponiho palác 3.jpg|
