The keys to defending cities are:
Defence in Depth
Use the Existing Topography
Keep the Enemy Guessing
As it has been necessary to fortify towns and cities to defeat the Martians, lessons have been hard learned. Successful methods and unsuccessful methods are examined and modified to provide a continuous series of obstacles to the Martian Invader.
Mines of various types.
Rings of minefields offer a passive defence, but they have several weaknesses.
It is necessary to provide lanes clear of mines to allow access to and from the city. One way to deal with the clear lanes in to make lanes straight and well marked, then hastily sow them shut when the enemy approaches.
Different mines are needed for different threats. The methods of sowing mines are well published. The Martians have one always effective means of breaching minefields: They send equipment through and clear lanes by brute force. Mines do not stop the Martians, but it costs the martians dearly to breach the Minefields.
Traps
A series of holes of various sizes and depths has proven to be a difficult barrier to the Martians. Ditches are not very difficult for the Martians to cross, but an irregular pattern of pits works.
Dragon's Teeth slow down the Tripods, but they have scant effect on drones.
Hedgehogs have to be arrayed in random patterns of random size to be effective.
A good material for traps and barricades is concrete reinforced with steel wire or rods. This is a good combination of the strength needed andthe heat resistance needed to be a barrier to the machines and resist the heat rays.
Edison Wires
The more layers of Edison Wires, the better. The Martians will sacrifice machines to defeat them. Make these sacrifices costly.
Walls
Tall walls made of reinforced concrete. Engineers and scientists and master masons have worked together to design ways to build walls fast and tall and thick. Watching the PhDs work with the barely-literate workmen learning from each other shows us the real hope for humanity. We are many, we have one purpose, and we work together.
The walls will stop the Martians, at least for a while
Guns
Heavy guns with interlocking fields of fire guided by people calling in the fire. Guns destroy Tripods. Add guns to any defence and the Martians have to sacrifice even more material to breach the defences.
HOPE
Any Physical obstacle man can make the Martians can destroy. Any system of defences that man can be destroyed by the Martians. It requires the hope and determination and courage of the human defenders to defeat the Martians.
We are tougher than those accursed things. We must teach them that lesson.

It is extremely resistant to heat and since the Martians don't use many weapons that have any real impact, a relatively thin wall (which would be quickly reduced to rubble by cannon fire) could still be effective. I could even see prefabricated walls (like giant Lego blocks perhaps) being introduced to allow fortifications to be constructed quickly.
