Yes it is because it has structure like an aromatic ring & its resonance....
The lone pair on nitrogen is in the p orbital so it is involved in a pi-electron aromatic system. Hence pyrrole is not very nucleophilic and is only weakly basic at nitrogen....
The 4 electrons from the double bonds and the lone pair on the nitrogen give a total of 6 electrons, in accordance with Huckel's Rule (2_n+2). The molecule is planar and cyclic, so the three requirements for aromaticity have been met...........
