We present an overview and a brief report on the status of the STELLA project (abbreviation for STELLar Activity). The STELLA‐I telescope will be the first robotic telescope that feeds a bench‐mounted high‐resolution Echelle spectrograph with a set of 50 and 100 μm fibres and provides spectral resolutions of up to 47,000 with a 1 arcsec slit. The spectrograph is a white‐pupil design located in a separated temperature‐controlled room to guarantee long‐term stability. The building will have a roll‐off roof and is capable to host two telescopes. First light for STELLA‐I is planned for summer 2002. STELLA‐II is foreseen to be a photometric imaging telescope for the optical and near‐infrared wavelengths and will follow in 2003.
