  Motivated by the Costamante & Ghisellini (2002) predictions we investigated
if the blazar 1ES 1727+502 (z=0.055) is emitting very high energy (VHE, E>100
GeV) gamma rays. We observed the BL Lac object 1ES 1727+502 in stereoscopic
mode with the two MAGIC telescopes during 14 nights between May 6th and June
10th 2011, for a total effective observing time of 12.6 hours. For the study of
the multiwavelength spectral energy distribution (SED) we use simultaneous
optical R-band data from the KVA telescope, archival UV/optical and X-ray
observations by instruments UVOT and XRT on board of the Swift satellite and
high energy (HE, 0.1 GeV - 100 GeV) gamma-ray data from the Fermi-LAT
instrument. We detect, for the first time, VHE gamma-ray emission from 1ES
1727+502 at a statistical significance of 5.5 sigma. The integral flux above
150 GeV is estimated to be (2.1\pm0.4)% of the Crab Nebula flux and the
de-absorbed VHE spectrum has a photon index of (2.7\pm0.5). No significant
short-term variability was found in any of the wavebands presented here. We
model the SED using a one-zone synchrotron self-Compton model obtaining
parameters typical for this class of sources.
