Here is a brief history of Jerusalem since its destruction in AD 70:
After the destruction of Jerusalem by Titus in AD 70, the city lay dormant and unoccupied except for a few Roman military camps. Jerusalem was so thoroughly destroyed that much of the rubble was left in place. But eventually, new buildings were built on top of the old. This cycle has repeated itself many times. As a result, the ground level of Jerusalem has been raised significantly over the last 2,000 years. For example, some of the exposed streets that go back to the Roman period are more than 10 feet below the level of the current city streets.
Roman Emperor Hadrian rebuilt Jerusalem on a Roman plan. This included the usual cardo (or “main street”), which went north and south, a forum, Roman temples, etc. He also expanded the city walls to extend further north. These walls reached several blocks beyond the northern boundary of the “Old City” walls we see today.
Another huge change to the city occurred after Roman Emperor Constantine converted to Christianity. He began to pour resources into the region. This started what is now known as the Byzantine era. During the Byzantine era, the population of Jerusalem increased. Many new buildings, including churches, were constructed during the 4th through 6th centuries. The most famous of these churches include the Church of the Holy Sepulcher, the Church of the Apostles, and the Nea Church. But all of these churches suffered damage or destruction in later invasions by Persians and Muslims.
So, that’s a brief history of Jerusalem since its destruction during the first century AD.
