Among the monuments of this age discovered in the surrounding districts are the rock hewn tombs of Spata, accidentally revealed by a landslip in 1877, and the domed sepulchre at Menidi, near the ancient Acharnae, excavated by Lolling in 1879.
With fine cloisters (partly destroyed by a landslip in 1899) is now used as an hotel.
They are preserved to a considerable height on all sides, except where the ravine is precipitous and they have been carried away by a landslip; they are for the most part built of irregular blocks of great size in the so-called " Cyclopian " style; but certain portions, notably that near the chief gate, are built in almost regular courses of squared stones; there are also some later repairs in polygonal masonry.
The temple, which (as inscriptions show) was dedicated to Artemis, had been half-buried by a landslip from the acropolis hill in the historic earthquake of 17 A.D.
In the outer valleys of the Himalaya the sides are generally steep, so steep as to be liable to landslip, whilst the streams are still cutting down the river beds and have not yet reached the stage of equilibrium.
