the top. The view obtained of the city below is magnificent. The Vestner
Thurm, like the whole Imperial castle, passed at length into the care of
the town, which kept its Tower watch here as early as the fourteenth
century.

The well which supplied the second plateau with water, the "Deep Well,"
as it is called, stands in the center, surrounded by a wall. It is 335
feet deep, hewn out of the solid rock, and is said to have been wrought
by the hands of prisoners, and to have been the labor of thirty years.
So much we can easily believe as we lean over and count the six seconds
that elapse between the time when an object is dropt from the top to the
time when it strikes the water beneath. Passages lead from the water's
edge to the Rathaus, by which prisoners came formerly to draw water, and
to St. John's Churchyard and other points outside the town. The system
of underground passages here and in the Castle was an important part of
the defenses, affording as it did a means of communication with the
outer world and as a last extremity, in the case of a siege, a means of
escape.

Meanwhile, leaving the Deep Well and passing some insignificant modern
dwellings, and leaving beneath us on the left the Himmelsthor, let us
approach the summit of the rock and the buildings of the Kaiserburg
itself. As we advance to the gateway with the intention of ringing the
bell for the castellan, we notice on the left the Double Chapel,
attaching to the Heathen Tower, the lower part of which is encrusted
with what were once supposed to be Pagan images. The Tower protrudes
beyond the face of the third plateau, and its prominence may indicate
the width of a trench, now filled in, which was once dug outside the
enclosing wall of the summit of the rock. The whole of the south side of
this plateau is taken up by the "Palast" (the vast hall, two stories
