The graphic art collection includes hand drawings and paintings using various techniques - such as pencil, pen and chalk drawings, watercolours, oil paintings and gouaches – as well as prints using various techniques – such as etchings, woodcuts, aquatints and lithographs. The collection spans six centuries and today comprises around 3,300 individual objects (of which around 1,800 are graphics and 1,500 prints) and is constantly growing through bequests and donations.

The oldest piece in the collection dates from 1599 and is a small pen/brush drawing with ink/bister of ‘Mercuria’, but the attributes depicted make it likely that it is Minerva, goddess of wisdom and war.

The graphic works from the estate of the glass painter and draughtswoman Lucia Jirgal (1914-2007) make up a large part of the collection. This covers large parts of the versatile artist's oeuvre. One focus of her work was the design of church interiors, in particular church windows. Despite numerous commissions - to date, around thirty churches in Vienna, Lower Austria, Burgenland and Upper Austria are known to have been decorated with sacred art by the Viennese artist – Lucia Jirgal is not known to many. The aim of the revision and digitisation is also to create a basis for research into the work of this Austrian artist.

From 1942 to 1948, Lucia Jirgal also worked as an assistant to Richard Teschner. Through her estate, sketches, photographs, correspondence and also a copy of a sketchbook and workbook by the famous Viennese Art Nouveau artist came to Heiligenkreuz Abbey.

In times of digital transformation, works that once belonged to the same context and are now in different collections can be put back into context. Digitisation efforts make it possible to show sketches for the same projects or even drafts and fully developed works in their original context of origin. Corresponding examples from the Richard Teschner collection are pencil sketches for book illustrations for Gulliver's Travels.

Comparable pieces can be found in the collection of the Albertina in Vienna. The entry for the sketches from Heiligenkreuz Abbey on museum-digital contains links to the other pieces in the Albertina.

Another highlight of the collection is a group of watercolours by Erwin Pendl (1875-1926), who painted various views of Heiligenkreuz.

The four dactyliotheques are also interesting. These are hinged, book-like boxes with an intermediate layer measuring 34 x 25 x 5.5 cm, whose top and bottom can be opened to reveal the intermediate layer. This creates four panels that could be used for mounting the plaster casts.

The Venetian artist Giovanni Giuliani (1664-1744) worked at Heiligenkreuz Abbey for over thirty years. The Trinity Column in the abbey courtyard, the choir stalls in the abbey church and the monumental sculptures in the cloister are particularly noteworthy. The art collection includes his bozzetti from the 18th century.

The glass art and bronze sculptures of Cistercian Father Raphael Statt OCist form a separate part of the collection. The artist works in a studio belonging to the monastery and is constantly adding to the collection.
