Ep 7. World's Tallest Church

In Building Giants season 1 episode 7, titled "World's Tallest Church," viewers are taken on a journey to witness the construction of the Ulm Minster- a majestic gothic cathedral that is known as the world's tallest and Germany's largest church. The episode is a fascinating insight into the intricate and complex process of building a structure that stands tall at a towering 161.5 meters or 530 feet.

The show kicks off by showcasing the daunting task of laying the foundation. Viewers witness the excavation process in which builders have to dig more than 10 feet deep to get to the bedrock, which will be the base of the foundation. The team then lays a concrete base and steel frame on top that will support the rest of the structure.

As the project takes shape, we see how the building team has to overcome several challenges to make sure that the church can withstand strong winds and natural disasters. They install a wind turbine on top of the cathedral to help counterbalance the wind load, and reinforce the structure by using specially engineered steel girders that can support the weight of the church's towers and dome.

One of the standout moments in the episode is when we see how the team built the church's giant tower. The tower is made up of eight smaller sections, which the team constructs on the ground before lifting each of them to their individual places on the church. The biggest challenge comes when they have to lift the topmost section, which weighs 14 tons, and is nearly 49 meters high. The entire operation requires expert coordination and precision.

The construction of the church's signature dome is also a highlight of the episode. Viewers get a chance to observe how the builders construct the dome using a technique called "falsework," which involves building a temporary support system for the new structure to stand on, while under construction. As the dome slowly takes shape, the team installs a complex system of steel chains and cables that will support the immense weight of the dome as it is built.

Finally, viewers are treated to the spectacle of the completed church, with its stunning spires and intricate details. From the intricate stonework to the towering Gothic arches, the cathedral is a testament to the expertise, dedication, and precision of the team of builders.

Overall, Building Giants season 1 episode 7, "World's Tallest Church," is an awe-inspiring journey through the process of constructing a magnificent towering cathedral. The episode captures all the triumphs, challenges, and intricacies of building such a massive structure. It's a must-watch for anyone interested in architecture or engineering, or anyone who just wants to marvel at the incredible feats that human beings are capable of achieving.
