Roman Catholic Diocese of Wiener Neustadt
Suppressed diocese of the Catholic Church in Austria

The former Diocese of Wiener Neustadt in Lower Austria existed from 1469 to 1785. In 1990, it was re-established as a titular see which is held by the bishop for the Military Services in Austria.
History
Upon the request of the Emperor Frederick III, the diocese was created by Pope Paul II on 14 January 1469, and was immediately subject to the Holy See. At first it was coterminous with the town of Wiener Neustadt.
In 1769 the new parish of Theresienfeld was added and in 1784 its territory was extended from Wiener-Neustadt to the boundary of Styria. On 21 April 1785, the see was incorporated in the Archdiocese of Vienna by Emperor Joseph II. Its last bishop, Johann Heinrich von Kerens, S.J. (1775–1785), and his cathedral chapter were transferred to the newly erected Diocese of Sankt Pölten.
Cathedral
The Late-Romanesque Dom or cathedral was consecrated in 1279 and remained the cathedral from 1469 to 1785. The choir stalls and transept, in Gothic style, are from the 14th century. In the late 15th century 12 statues of the Apostles were added in the apse, while the bust of Cardinal Melchior Klesl is attributed to Gian Lorenzo Bernini.

Begin with the source’s own compact description: “Roman Catholic Diocese of Wiener Neustadt” is suppressed diocese of the Catholic Church in Austria. The dossier treats that line as a proposition to test through Roman, Catholic and Diocese, not as a finished interpretation.
Why this record matters
The phrase “suppressed diocese of the Catholic Church in Austria” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q1231931. VIAF identifies the subject as 239936272. Authority coordinates are 47.815, 16.242. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1469, 1785, 1990 and 1769.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
