Today, on the Fast of Av, Jews throughout the world mourn the destruction of the two Holy Temples of Jerusalem and pray for the rebuilding of the Third Temple. But one organization has been doing a lot more than just praying. The Temple Institute has released a modern three-dimensional architectural rendition of the future Third Holy Temple, utilizing the latest building material and techniques.
The vivid, three-minute video walks viewers through the main sanctuary, showcasing decades of research and tens of innovative Halakhic (Jewish law) solutions to various perplexing issues that were resolved to create fully functional, ready-to-use plans.
While staying true to the Halakhic requirements and dimensions, the project also adds some clear modern twists. SOURCE
