Towers in the southern wall
... between the Oostpoort and the Rotterdamse Poort
Oostpoort
St. Agnieten Tooren
Leeuwenhoek rented this tower from the city in on December 5, 1693, according to the city's Consentboek (permit or license book) for 1664-1794 (image below; OAD inv. 650.2 fol. 31). See the event under Learn more below.

St. Sebastiaens Tooren
The earlier maps show this tower, along with St. Agnieten Tooren, as being in front of the wall, a break in what look like bushes partway up. Deventer's map of 1556 and Blaeu's Delft Batavorum map of 1649 show a third tower between St. Agnieten Tooren and St. Sebastiaens Tooren. They are all bastions (sometimes called bulwarks), as high as the wall and without top or roof. Bastions were most commonly pointed, but the Delft bastions were round, leaving a dead zone in front that gunfire from the sides could not reach.
On the post-fire maps of 1536 and on the Kaart Figuratief of 1678, there is no third tower between them. Both are full towers, that is, higher than the wall and covered with a pointed roof. Adding a back wall, often flush with the regular city wall, created a small room within.
All the maps show them as similar, and on the Kaart Figuratief they look like different views of the two towers between the Waterslootse Poort and the Schoolpoort, that is, the St. Michiels Tooren and the St. Hyronimus Toorn.

Oosterwycse Tooren
A roundel, unraised and unfortified on the corner of one of the bends in the singel between the Rotterdamse Poort and the Ooostpoort. Although it is not clear from the Kaart Figuratief, it must have had a raised floor so that shooters could aim their weapons over the wall. It provided excellent angles for defense. The Deventer map of 1556 has a windmill set back a little as a separate structure.
Henegouse Toorn
A round tower set between the wall and the singel, protruding a little into the singel. It had two stories with a pointed roof and two rows of windows.
