Kastellaun, Kirche Kreuzauffindung

Renovation and enlargement | II/21 +5 Ext. +11 TM | 2020

The Church of the Finding of the Cross in Kastellaun was built in 1899-1902 as a three-aisled basilica in neo-gothic style with transepts and choir side aisles. The organ was completed in 1902, the year the church was dedicated, by the Gerhardt brothers from Boppard. It had two manuals and pedal, 19 stops and pneumatic action. The specification was of its time, in high romantic style with predominantly fundamental tonal colours and complete absence of reeds.

Apart from the front pipes replaced in zinc in WWI, the organ survived in original state until the 1970s, when it was rebuilt by Klein & Son (Obersteinbach) with far-reaching alterations. The old console, built into the side of the case, was replaced by a mobile one, the action converted to electro-pneumatic and the specification ‘barockised’ by the inclusion of higher-pitched stops. Fortunately, the greater part of the pipe material was reused.

In 1999 Mayer (Hausweiler) substituted a new Oboe 8 for the neo-baroque Zimbel 3f. In the course of time tonal shortcomings and technical malfunctions became more and more apparent.

The aim of the planned rebuilding is to create an organ of high tonal and technical quality, which offers new artistic perspectives for the future.  The previously unreliable and musically unsatisfying instrument will undergo a complete rebuilding with the tonal substance carefully extended.

The historic pipework has great tonal potential and, after careful restoration, will be brought back close to the original concept. Where necessary, missing or cut down pipes will be reconstructed.  The front pipes will be re-gilded. In addition there will be two new tremulants, and a swell box for Manual II.

A thorough revoicing of the whole organ will lead to a characterful and homogeneous tonal palette, unifying all registers into a whole and with romantic warmth bringing its colour and carrying power to full effect.

Among other things on the technical side, work is needed on the building frame, as is a re-positioning of the Pedal windchests. The whole organ will be moved forward by 30cm to improve maintenance access. The case will receive a hitherto missing rear wall and tonally transparent infills in the lower part. The side walls will be renewed in stylistically correct fashion.

The windchests will be overhauled and electrics brought up to modern standards and fitted with a BUS (MIDI) facility. The electric console will be converted to accommodate the new specification. The wind system needs to be redesigned and a new blower provided.

Enlargements to the specification are planned for the future. In preparation for these the space will be provided on added cone valve windchsests.

Further information on the project is available from website of the Musikforum Kastellaun.
