History

Tecklenburg Castle is situated in the municipality of Tecklenburg, Germany. It was originally built around the year 1100 by the Dutch Count of Zutphen, who sought to oversee and collect tolls along a key trade route stretching from Lübeck down to Cologne. This important roadway connected several historic cities including Bremen and Münster. By the late 12th century, around 1184, Tecklenburg had become recognized as one of the largest and most formidable hilltop castles in northern Germany.

In the period between 1168 and 1190, control of the surrounding territory known as the County of Tecklenburg transferred to Archbishop Philip of Cologne. Despite this, Count Symon maintained possession of the castle through a feudal arrangement. The castle and its lands were significant in the archbishops’ efforts to assert authority over the Westphalia region. However, in 1226, the castle and town came under papal ban after providing refuge to Frederick of Isenberg, who was accused of killing Archbishop Engelbert of Cologne. The following year, in 1227, the Cologne church confiscated the castle, and its sovereignty shifted to the Bishop of Osnabrück by 1282.

Following the death of the Counts of Tecklenburg in 1262, ownership passed sequentially to the Counts of Bentheim and then to the Counts of Schwerin from 1328 until 1562. During this era, northern parts of the county were lost to the Bishopric of Münster in 1400, diminishing the castle’s strategic value as trade routes evolved and territorial boundaries changed.

The 16th century marked a religious turning point under Count Conrad, who led Tecklenburg to become the first territory in Westphalia to embrace the Protestant Reformation in 1527. The county also took part in the Schmalkaldic League from 1538, an alliance of Protestant territories. To strengthen defenses during these religious conflicts, the castle’s fortifications were expanded, including the addition of a bastion in its northeast corner. Countess Anna, Conrad’s daughter, later made the castle more comfortable for residence by enlarging windows and creating a new entrance from the northeast side via Schlossstraße. These changes partly covered the bastion previously built. The 17th century saw the construction of the Mauritz Gate at this entrance, with elements of its decorated façade still visible today.

Ownership of the county changed hands over the following centuries, involving families such as Bentheim-Tecklenburg and Solms-Braunfels. In 1707, Tecklenburg lost its sovereignty when sold to the Kingdom of Prussia. Plans to transform the castle into a modern fortress were unsuccessful, and by 1744 the castle began to be dismantled for building materials in the area, leading to its gradual ruin.

Efforts to preserve the castle started in the late 1800s. Among these was the construction of the Wierturm, a brick observation tower built in 1884 as a memorial to Johann Weyer, a court doctor. Since 1927, the castle’s outer courtyard has been used as a venue for theatrical performances, and from 1949 onward, it became home to the Tecklenburg Open-Air Theatre, which can accommodate around 2,300 spectators.

Remains

Tecklenburg Castle is a hilltop fortress positioned on the Burgberg hill, approximately 170 meters above sea level within the Teutoburg Forest. Its layout consists of two main areas: an outer courtyard, often called the forecourt, and an inner courtyard, the main castle, which were separated by a defensive moat and a protective embankment. Parts of this earthwork and wall structure remain intact, offering insight into the castle’s original defenses.

On top of this embankment once stood the Hakenturm, sometimes known as the Schiffsturm. This pentagonal tower was the tallest structure within the castle complex. Today, only its foundation remains, reaching the height where the embankment itself crowns. The precise details of this tower’s construction and appearance survive primarily through archaeological study rather than standing walls.

The main entrance from the northeast, developed in the 17th century, features the Mauritz Gate. This gate’s lower floor and parts of the floor above have been preserved, showcasing richly decorated stonework, including a distinct frieze adorned with coats of arms. This entrance marks the later phase of the castle’s use when residential comfort and representational aspects gained importance.

Within the inner courtyard, buildings enclosed the space on three sides. While above-ground structures have mostly vanished, foundation remnants outline their former locations. Among these ruins is a notably large room known locally as the Krönchen. Tradition identifies this as the castle chapel, although this has not been conclusively verified by archaeological evidence.

The 16th-century bastion constructed in the northeastern section was largely buried when the embankment for Schlossstraße was built. It was uncovered in 1944 during work creating an air raid shelter, revealing vaulted stone structures characteristic of military architecture of the period.

Many stones from the castle were reused in local buildings after its decline. Examples include a Renaissance-style fireplace in the nearby Drei Kronen hotel, decorative bridge piers at the Haus Marck estate, and sections of the town’s former prison and courthouse. These reused materials help trace the castle’s influence on local construction.

Among the castle’s surviving features is the Wierturm, a round observation tower made of brick situated on the ramparts between the two courtyards. It offers extensive views of Tecklenburg and the surrounding Münsterland plains. Access is managed through a key system held by the local tourist office.

While the full original design and construction phases of Tecklenburg Castle have not been fully determined, historical depictions such as the engraving by Solms from the 17th century provide valuable visual references contributing to current understanding of the site’s appearance during its period of occupation.
