virtual excursion 360°Jablje Castle stands at the foot of Rašica near Loka pri Mengeš, on the edge of the Mengeš Plain. Its location was strategically chosen: it rises on a rocky cliff of karst terrain, beneath which lies a cave with the sinking stream Šumberk. This natural feature allowed the castle to secure its own water supply, as it had a well right in the inner courtyard. Surrounded by the forests of Rašica and open towards the plain, the castle was both a safe refuge and a vantage point, which was of great importance in the Middle Ages.
The first mentions of the castle date back to 1268, while its present Renaissance appearance was shaped around 1530 by the noble Lamberg family. Later it was owned by the Raspi family, the Mosconi barons, and from 1780 until the end of the Second World War by the Lichtenberg barons. The castle survived the war without major damage, but after 1945 it was nationalized, plundered, and converted into a residential building and an experimental agricultural center of the Faculty of Biology. Nevertheless, valuable artistic features were preserved, among them the Baroque frescoes of painter Franc Jelovšek, which adorn the southwest tower. After the earthquake of 1895 the castle was renovated, and the last thorough restoration took place between 2000 and 2004, when its former splendor was restored.
Jablje Castle is designed as a Renaissance manor with later Baroque additions. Its architectural image developed over the centuries, which is today evident in the combination of stylistic elements. The castle has a rectangular layout with an inner courtyard, typical of Renaissance castle complexes. At the corners stand four towers, the southwest one being especially famous for Jelovšek’s frescoes. The courtyard was once the central space of economic and social life, today it gives the castle its characteristic openness. The towers were originally intended for defense, but in the Baroque period they acquired a more representative role. Their massiveness gives the castle an impression of solidity, while the window openings were later enlarged to provide more light. The facades are relatively simple, yet emphasized with Baroque window frames and portals. Inside lies rich decoration – frescoes, stucco, and paintings created in the 18th century. The most valuable artistic element are Jelovšek’s frescoes, depicting allegorical and religious motifs, considered among the highlights of Slovenian Baroque painting. The rooms are arranged around the courtyard, allowing functional connection between residential and economic parts. Fireplaces, vaults, and staircases have been preserved, testifying to the Renaissance origin. In the Baroque period, representative halls were added, intended for receptions and social events. The castle is surrounded by a park, laid out in the Baroque era as a formal garden with walking paths.
Today Jablje Castle is a cultural monument of national importance. It houses the Center for European Future, which organizes international conferences and protocol events. In 2008, during Slovenia’s presidency of the European Union, it was one of the main protocol venues. In addition to official functions, the castle is popular for weddings, business events, exhibitions, and cultural gatherings, as it combines historical atmosphere with modern infrastructure. The restored park and castle premises create a space that connects medieval heritage with modern use.

In the oldest records from the 13th century, the castle appears under the German name Habach.
The name consists of two parts:
Hab- from Old German Habe (property, possession), or possibly a personal name.
-ach is a common suffix in German toponyms, denoting a watercourse or valley (from Old High German aha = water, stream).
Thus the original name likely meant “estate by the water” or “Hab’s valley.”
Later the name was Slovene-ized into Jablje, connected with local usage.
The Slovene form refers to the apple tree (Malus domestica), as the Mengeš Plain is known for orchards and apple cultivation.
The transition from Habach to Jablje is a typical example of linguistic adaptation: a foreign name reshaped into a familiar, understandable local form.
Similar cases exist elsewhere in Slovenia, where German names were replaced by Slovene ones, often linked to nature or agriculture.
Etymological development:
Habach (German medieval form) → meaning: estate by the water.
Jablje (Slovene form) → meaning: place associated with apple trees.
The modern name combines historical continuity with local natural features, typical of Slovene toponymy.
