The root offers stubborn resistance.

The employee of the company "Freelance Baumpflege" climbed a ladder to get to her.

He has to pull hard before the plant detaches itself from the ground.

Ivy in particular, and moss in other places, grows on the thick wall that borders the Hayn Castle complex in the Dreieichen district of Dreieichenhain to the north-west.

Sometimes the plants cannot be completely removed: branches as thick as an arm that made their way through the wall over time were only sawed off.

Remains of roots can still be seen on a number of stones.

On behalf of the city of Dreieich, the company and several employees cleared the old walls of vegetation on the approximately 165-meter-long section to Solmische-Weiher-Straße over two days at the beginning of the week.

The work was coordinated with both the Dreieichenhain history and homeland association and the lower monument protection authority of the Offenbach district.

In 1931, the association acquired the listed castle complex, whose history begins around 1080: At that time, Eberhard von Hagen had a hilltop castle built in the imperial Bannforst Dreieich.

Wall belongs to part of the city

Palas and keep, the so-called round tower, were added in 1180 under the lords of Munzenberg.

The castle wall probably also dates from the 11th century;

according to the club's chairman Detlef Odenwald, "but no one really knows".

However, the wall that encloses the castle area does not belong to the historical and local history association in its entirety: the section on Solmische-Weiher-Straße, which later becomes the city wall of Dreieichenhain, is owned by the city.

The association does everything it can to maintain and maintain the castle.

Just a few months ago, the only surviving wall of the tower hill castle, which rises 23 meters into the sky, was extensively photogrammetrically examined.

Odenwald made it clear that the tower hill castle was to be secured in the long term.

After all, it is an important cultural monument of the region that characterizes the entire complex.

The association has invested more than one million euros over the past few years and decades to maintain the old walls.

On the section of the wall owned by the city, the municipal housing company Dreieichbau became active, which also provides building construction services for the city.

Along the Solmi pond system, the wall reaches a height of six to seven meters on the outside.

Inside, the courtyard was once filled up;

there the walls are only about three meters high.

Four years ago, the association, in coordination with the monument protection authorities, had a breakthrough made through the wall to Solmische-Weiher-Straße, which is intended to serve as a second escape route for larger events, such as the Dreieichenhain Castle Festival.

At that time, a usage agreement was concluded with the city, said Odenwald.
