[1] [2] The abbey church, dedicated the Nativity of Mary (Mariä Geburt), was consecrated in 1136 and remodeled in the Baroque style in the seventeenth century.

From 1634 on, the Habsburg rulers had the facilities rebuilt in the Baroque style, continued by the architects Jakob Prandtauer and Donato Felice d'Allio.

The plans to embellish the monastery on the scale of an Austrian Escorial were later resumed by the Neoclassical architect Joseph Kornhäusel, though only small parts were actually carried out.

In 1879, the abbey church and monastery were restored according to plans by Friedrich von Schmidt, and the neo-Gothic twin steeples were erected.

Its three parts comprise 45 gilded copper plates modeled on Byzantine paragons, similar to the Shrine of the Three Kings at Cologne Cathedral.

[3] During the Investiture Controversy in the early twelfth century, Margrave Leopold III of Babenberg sided with the Papacy against Emperor Henry IV.

Following his marriage, Leopold initiated plans to build a castle on Leopoldsberg for his new residence, which had formerly been at Gars am Kamp and Tulln an der Donau.

[4] According to legend, Leopold was standing with his wife on the balcony of their new castle when Agnes' veil was carried away by a strong gust of wind.

[6] In 1220, Duke Leopold VI of Austria selected a Burgundian master architect to build the Capella Speziosa chapel beside the convent.

[9] In the fall of 1683, a massive Ottoman army under the leadership of Kara Mustafa Pasha laid siege to Vienna and threatened Klosterneuburg.

[9] The defense of Klosterneuburg turned out to be strategically important because it served as flank protection during the rescue of Vienna by the Christian forces under the leadership of King John III Sobieski.

Emperor Charles VI now sought to make Klosterneuburg a secular and spiritual center after the model of the Escorial in Spain.

[10] Construction of the monastery continued for ten years, under Donato Felice d'Allio, who was inspired by Joseph Emanuel Fischer von Erlach, the master architect of Vienna at the time.

Inspired by the Age of Enlightenment, Joseph was anxious to reduce the power of the church, to relieve the peasantry of feudal burdens, and to remove restrictions on trade and knowledge.

[2] Provost Alipius Linda, elected in 1937, guided the community wisely through both the Nazi period and the subsequent Communist occupation.

[2] During the post-war period, Provost Gebhard Koberger presided over the rebuilding of the abbey's financial condition, as well as the reconstruction of several of the monastery's churches which had been damaged or destroyed by the bombing.

Its three parts comprise 51 gilded copper plates modeled on Byzantine paragons, similar to the Shrine of the Three Kings at Cologne Cathedral.

According to the biblical exegesis, the depictions are split into three rows of the eras of Adam and Noah, of Abraham, David and the Babylonian captivity and finally of Jesus' life, placed in the central part.

[1] American scholar Elfie Raymond, professor of philosophy and hermeneutics at Sarah Lawrence College of New York produced an online catalog of the typology of virtues found in the theological program.

Smaller campaigns such as child protection centers in India and Honduras, women's aid projects in Afghanistan or an eye clinic in South Sudan are also funded.

With the exception of two four-year lapses at the end of the sixteenth and beginning of the seventeenth centuries, the community has enjoyed stable and continual self–governance for nearly 900 years.
