Abstract: | In this paper we have discussed two models of domain walls within the framework of Lyra geometry. An exact solution is obtained
for a thick non static domain wall. The space time is non singular both in its spatial and temporal behavior and the gravitational
field experienced by a test particle is attractive. It is found that these exists no particle horizon in our case. Also we
have presented a spherical domain wall with nonvanishing stress components in the direction perpendicular to the plane of
the wall. The gravitational field of the domain wall is shown to be attractive in nature.
