In the course of history many valuable buildings and monuments were destroyed.
This is particularly true for the period of Romanticism, from which only sparse remains have been left (parish church of Guessing, Fischerkirche Rust).
From Gothic times many churches (Fischerkirche Rust with murals and Holy Trinity altar; Oslip, Eisenstadt cathedral, Mattersburg, Stadtschlaining, Gaas and Eberau) and castles have remained.
The Renaissance period has only left scarce traces, due to the Turkish Wars in the 16th centuries and other fierce battles only few fortifications and castles, like Castle Forchtenstein, have survived.
During the Baroque, the nobles of the land (Esterházy, Batthyány, Náasdy and Stotzingen) had numerous churches, castles and mansions built. Artists and architects like Lukas von Hildebrandt, Joseph Emanuel Fischer von Erlach, Franz Anton Maulbertsch and Martino Altomonte showed their skills in the Burgenland.
The churches in Frauenkirchen (by Martinelli) and Loretto are significant pilgrimage churches. The most splendid castles outside of Eisenstadt were built in Halbturn (Lukas von Hildebrandt, frescoes by Maulbertsch), Kittsee and Kobersdorf.
During the Classicism buildings from former time like Castle Esterházy in Eisenstadt or Castle Draskovich in Guessing were rebuilt or extended.
