Summary: In this paper general solutions are found for domain walls in Lyra geometry in the plane symmetric spacetime metric given by Taub. Expressions for the energy density and pressure of domain walls are derived in both cases of uniform and time varying displacement field \(\beta\). It is also shown that the results obtained by F. Rahaman et al. [Int. J. Mod. Phys. D 10, 735–739 (2001)] are particular case of our solutions. Finally, the geodesic equations and acceleration of the test particle are discussed.
