Draw a vertical rectangle on a sheet of paper. But remember, it has to be tilted to the right.
The top of the tower
Draw a horizontal line on top of the rectangle, dividing it into two parts. The upper part must be very small.
Draw two vertical lines on the top to form a square inside.
Make a rounded bottom of the tower.
Erase the unnecessary lines and round the top.
Encircle the edges of the tower using the curved lines.
Now divide the tower into seven parts. It will be the floors. The first floor should be bigger than the others.
Make the construction look like a cylinder, slightly correcting the drawing.
Erase unnecessary details. Note that the floor lines should also be rounded.
Add more lines.
There are arched passages on each floor of the tower. Depict them. Let’s start from the first floor. The arches look like a regular entrance only with a rounded top.
Draw the arches on the other floors.
Draw three small arches at the top of the tower.
Give some volume to the passages, adding small details.
