  A novel class of Einstein vacua is presented, which possess non-vanishing
cosmological constant and accelerating horizon with the topology of $S^{D-3}$
fibration over $S^{1}$. After Euclideanization, the solution describes a
conformally distorted $S^{D-1}$ fibration over $S^1$, which is smooth, compact
and inhomogeneous, and can be regarded as analogue of Don Page's gravitational
instanton.
