We have imaged the inner 0.1 pc of the archetypal radio jet in the nearby radio galaxy, 3C274 (Virgo A), with two epochs of intercontinental, very-long-baseline interferometry (VLBI) at a wavelength of 1.3 cm. These images have the highest linear resolution (1.6 x 10-2 pc) achieved on an extragalactic radio jet. At this resolution, we find a approximately 4 mas (0.3 pc) long jet composed of several components. A lower resolution image detects the jet to approximately 25 mas (2 pc) from the presumed core. The jet appears well collimated (opening angle approximately 20 deg), and has a morphology similar to that on larger scales, even though these dimensions approach within 102 Schwarzschild radii of the putative supermassive (3 x 109 solar mass black hole. The position angle of the jet (276 deg +/- 4 deg) near the presumed core (less than 0.2 mas) is significantly different from that seen on larger scales (290 deg +/- 1 deg); there is evidence for a progressive northward curvature of the jet on the smallest size scales. No evidence foran accretion disk is seen. There is no evidence for proper motions of jet components at this resolution. Moderate variability of the core is found (approximately 30%) with a time scale of less than 5 months.
