Sinan: one for Pertev Paşa at Eyüp (see Chapter 18), the other for
Ahmet Paşa in the garden of Mihrimah Camii at the Edirne Gate
(see Chapter 17). Unlike these, however, this one preserves its roof, a
low central dome flanked at each end by a shallow cradle-vault. The
efect is very pretty. The walls between the windows are revetted with
tiles, still of the best period; they are perhaps not quite so stunning
as those of Ibrahim Paşa, but they contain a lot of Armenian bole at
its most brilliant.
OTHER INSTITUTIONS OF THE ŞEHZADE COMPLEX
The medrese of the Şehzade foundation is on the far side of the
precinct, at the north-west corner. It is a handsome building of the
usual form. The south side, facing the mosque precinct, has a portico
but no cells. Opposite the entrance, instead of the usual dershane, is
an open loggia, the lecture hall itself being in the centre of the east
side; opposite, a passage between two cells leads to the lavatories. The
building has been well restored and is again in use as a residence for
university students.
In line with the medrese but farther east is the kervansaray, which
now serves as a science laboratory for the adjacent Vefa Lisesi. This
building is probably not by Sinan, though obviously contemporary,
or nearly so, with the rest of the complex. It has no door into the
mosque precinct but is entered from the other side. It is L-shaped,
the bottom stroke of the L consisting of a long, wide hall, its eight
domes supported on three columns down its length; perpendicular to
this is a block of eight cubicles with two spacious halls giving access
to them. This interesting building is in good shape and makes a fine
science laboratory.
Between the reservoir tank and the wall of the türbe garden a
gate in the east wall of the precinct leads out into a side street, Dede
Efendi Caddesi. Opposite, to the left, are the primary school and
public kitchen of the complex. The primary school, or mektep, is of
the usual type. The public kitchen, or imaret, consists of a spacious
courtyard, on one side of which are three double kitchens and a
large refectory, its four domes supported on three columns. This is a
charmingly proportioned and gracious building. It is now used as a
