  We report the detection (3 sigma significance level) of a strong iron
emission line in the X-ray spectrum of the afterglow of GRB 000214
(``Valentine's Day Burst'') observed by BeppoSAX. An emission line feature was
observed with a centroid energy of 4.7+/-0.2 keV which, if interpreted as
K-alpha emission from hydrogen-like iron, corresponds to a redshift of z=0.47.
The observed intensity (EW ~2 keV) and duration (tens of hours) of the line
give information on the distance, from the burst region, of the emitting
material (R>3x10^15 cm) and its mass (M>1.4 solar mass). These results are not
easily reconciled with the binary merger and hypernova models for gamma ray
bursts.
