The orchestra was formed in 2017 through the merger of the Thüringen Philharmonie Gotha with the Stadtorchester Eisenach [de].
[3] Dirigenten des Suhler Orchesters waren Siegfried Geißler, Claus Peter Flor and Olaf Koch gewesen.
[6] On 7 September 2017, the merged orchestra gave its first entitlement concert at the Stadthalle Gotha under the motto "Music in Fusion".
In addition to several concert series in Gotha, the Thuringia Philharmonic Orchestra held the annual "Whitsun Festival" at Friedenstein Palace in Gotha in the Ekhof-Theater [de], the oldest completely preserved palace theatre in the world.
In 2001, on the occasion of the 350th anniversary of the founding of the Gotha Court Orchestra - whose tradition was continued by the Thuringia Philharmonic Orchestra Gotha-Suhl - the Baroque Festival was newly introduced, which has since been organised annually by the Friedenstein Palace Gotha Foundation.
The CD series Musik am Gothaer Hof (Music at the Gotha Court) has received several awards: it presents composers such as Georg Anton Benda, Andreas Romberg, Johann Ludwig Böhner, Louis Spohr and other personalities of Gotha's musical life in the 17th and 18th centuries.
