%X Motivated by recent detections of pulsar wind nebulae in very-high-energy(VHE) gamma rays, a systematic search for VHE gamma-ray sources associated withenergetic pulsars was performed, using data obtained with the H.E.S.S. (HighEnergy Stereoscopic System) instrument. The search for VHE gamma-ray sourcesnear the pulsar PSR J1718-3825 revealed the new VHE gamma-ray source HESSJ1718-385. We report on the results from the HESS data analysis of this sourceand on possible associations with the pulsar and at other wavelengths. Weinvestigate the energy spectrum of HESS J1718-385 that shows a clear peak. Thisis only the second time a VHE gamma-ray spectral maximum from a cosmic sourcewas observed, the first being the Vela X pulsar wind nebula.
