We report the discovery of a nearby massive white dwarf with He-H atmosphere. The white dwarf is located at a distance of \(74.5\pm0.9\) pc. Its radius, mass, effective temperature, H/He ratio and age are \(R=2500\pm100\) km, \(M=1.33\pm0.01\) \(\rm M_{\odot}\), \(T_{\mathrm{eff}}=31200\pm 1200\) K, \({\mathrm{H/He}}\sim0.1\) and \(330\pm40\) Myr, respectively. The observed spectrum is redshifted by \(V_{\mathrm{r}}=+240\pm15\) km s\(^{-1},\) which is mostly attributed to the gravitational redshift. The white dwarf shows a regular stable photometric variability with amplitude \(\Delta g\approx0.06^{\mathrm{m}}\) and period \(P=353.456\) s suggesting rapid rotation. This massive, hot and rapidly rotating white dwarf is likely to originate from the merging of close binary white dwarf system that avoided explosion in a thermonuclear type Ia supernova at the Carboniferous Period of the Earth history.
