Tairnbach Castle is a two-storey, ten-axle baroque building with a half-hipped roof.
The former park was built over and the former palace chapel was demolished in 1928.

...There are few villages the size of Tairnbach that can call a castle their own. This castle of the Lords of Ueberbruck zu Rodenstein celebrated its 275th birthday in 2011 and presents itself in a new guise inside and out. With a comprehensive renovation of the listed building, the historic structure was preserved and adapted to the current and future needs of the citizens.
According to current knowledge, there was a stately building or palace in Tairnbach more than 450 years ago. The stock book of the Lords of Hirschhorn from 1556, which reliably localizes all Tairnbach house plots, fields, meadows and vineyards in the district, also mentions a stately building complex of the Knights of Hirschhorn, the estate of Junker Hans.
Since 1638 the nobles of the Schertel von Burtenbach were landlords in Tairnbach and owned a building there that is referred to as a "fortified house", elsewhere as a "castle". In 1981, during excavation work in the castle cellar, a door and a window opening with a cavity behind it were found below ground level. Local historian Gerhard Höflin suspects that it is a remnant of the building fabric of the first, long-forgotten castle.

As a devout Catholic, Baron and castle builder Franz Caspar Ueberbruck von Rodenstein had an oratory, i.e. a castle chapel, built a year after the castle was completed. On August 13, 1737, Archbishop Franz Georg von Trier gave him permission to do so. The use of this chapel, in which services could be held, was agreed in writing. At Easter and Pentecost, however, the rulers and their employees were obliged to attend the fair in Mühlhausen.

The gem of the whole complex was the French-style chateau park. A wide staircase led down to him. During the lifetime of the last lady of the castle, Elisabeth Ueberbruck von Rodenstein (1858 – 1929), the park is said to have been a jewel of horticultural design. Designed by French garden architects, the park was the sanctuary of the castle manager, which he cared for with a lot of love and time.
All park paths were lined with low green shrubs, rare flowers and trees grew between the lawns. The lush green was only interrupted by the Tairnbach, which meandered through the middle of the stately garden. A bridge led over it, in the middle of which stood the garden and tea house of the Ueberbruck von Rodenstein family, exactly above the water.

In 1905, the municipality of Tairnbach became the proud owner of the castle. The castle and other properties were overwritten at a price of 170,000 gold marks. The municipal administration and several Tairnbach families moved into the building. Cigars were also produced indoors for a few years, and the artistically landscaped castle garden was transformed into a vegetable garden. On a June day in 1928, a cry echoed through the whole village: the castle is on fire!
At around 11 a.m. one morning, the flames erupted from the top floor of the building and quickly reduced the roof truss and some living rooms to rubble and ash. It was only thanks to the quick intervention of the volunteer fire brigade, which had been founded three years earlier, that the castle did not burn down to the foundations. The exact cause could never be elucidated.

In 1984, the community had the castle renovated, which was used by the Evangelical parish, the clubs and the community as a branch of the mayor's office. The Tairnbach palace building, once built and used by a small, aristocratic minority, is now open to all citizens after extensive renovation as a community center.
