Today, it appears everywhere in cities, roads and fields. You wake up one morning; you can’t get into your house because of a concrete block. You are on your way to a new hope; a concrete wall has set a barrier in front of you.

Concrete blocks are similar to every other product; the companies regulate the introduction of these blocks to the market with certain marketing words. For example, one says, in response to how a concrete block wall is produced: “For whatever purpose, concrete block walls must be placed on a solid concrete ground.” What solid ground is it possible to talk about? Is it solid ground on which all living things have disappeared? Or are the floors that hold, hide, and cover the past solid?

These walls rising on our borders are also building new borders within cities. Although this building block of security and surveillance architecture changes form and height from time to time, it retains itself as an archetype. What this archetype evokes is loss, destruction, and fear.

The dominant architectural narrative, built on these building blocks, has permeated its daily practice. It includes displacement, inability to return, and forced departure from home. Where destruction is occurring in the neighbourhoods, it brings a process of destruction and deterritorialisation.
