Many regions around the world are full of tunnels that are no longer in use More than ever, there are possibilities for rehabilitation, It's not always necessary to rebuild underground spaces, many of which already exist. But it was abandoned and forgotten completely now without any use or function. This happened in the city of Jober in Syria during the war, the area was completely destroyed and stretched beneath its surface with approximately 10 kilometres of tunnels enclosed by the darkness. These underground spaces are associated with different negative concepts. Finding a new use of neglected infrastructure changes the way people view these places. There is a need to give new life and meaning to these tunnels
The project aims to highlight the importance and value of untapped tunnels and demonstrate that abandoned tunnels can be rehabilitated into worthwhile tunnels. There is the potential to exploit these tunnels as part of urban land-use planning to raise together and the value of the area culturally, environmentally and socially.

These tunnels are located in the city making them accessible and suitable for daily tourist visits, it is about traveling to participate in real experiences with sites, events and handicrafts that reflect the history and cultural narrative of the place, while highlighting the different stages of their development over time
These underground journeys continue to draw attention, educate and inspire. The idea of a car tunnel was based on the principle of a visitor's time trip, driving visitors into a mysterious underground world that leads them into a space full of emotion and history.At the beginning of this trip there is a museum of memory of a place where the visitor's knowledge is graded from the past to the present and finally the future. We first talked about Jobar's agricultural history in the past through rural and environmental scenes and the stages of its development, and then the damage to the region in the present day puts visitors in a real booby trap while simulating the explosions and events that have passed through Syria, then the museum's journey ends displaying the future vision of the cityWhen visitors reach the tunnel level of -25 metres, they can walk on foot or via train with rubber tires. The tunnel is designed to be a museum path that progressively showcases the region's history, Light skylight in the cone-shaped strategic design allow natural light to penetrate deep into the tunnel. It creates a sense of greatness, establishes a visual connection with the sky and illuminates the art at the bottom with a gentle light spread. At night the effect is reflected as light emerges from the bottom and when it reaches the end of the tunnel it is almost a gift for us to give ourselves some comfort. A person finds a breathing space and it seems like you're outside just when you're at the end of the tunnel. Where the abandoned place that used to be a field hospital was transformed into a landscaped facility where we end up in the roof garden that was designed on several platforms to connect the underground area with the above-ground area using organic lines derived from leaves ratios to create contrast with the organized neighbourhood.
As for the strategy of the tunnel, since the tunnel's depth from the surface of the Earth is 6 metres it was designed to be an accessible underground hiking trail, essentially associated with the urban neighbourhood, the tunnel's roof was opened and a metal glass grid was used to be walkable as a visually attractive and vibrant passage that adds beauty and charm to the city and To emphasize the course of the tunnel, points and diamonds parallel to the course of the tunnel were taken to emphasize its importance. It is part of the memory of the place. Pockets in the path of the tunnel were expanded to display exhibits and statues of the area

Technical information: Attention was paid to the location of the foundation, the type of soil and other structural and natural principles around the site and considering the solutions strategy.
Technically leveraging tunnels to extend electricity and water systems. This solution needs to be strengthened
1 Suggested solution:
The suggested solution for the previous situations is lining tunnels by reinforced shotcrete
concrete and this method has been selected for the following reasons:
1. Shotcrete is a structural material, and it can be used as a permanent lining for tunnels.
2. Shotcrete concrete can be used to line tunnels with different profiles and different shapes. Shotcrete concrete high flowability allows concrete to form in any shape.
3. Shotcrete concrete gains strength rapidly, which provides support of the ground. This will limit the movement of the ground. Also, it will allow a degree of stress re-distribution.
