until the late 2nd century. Archeology shows that the wall was not made in haste to combat any type of emergency at Londinium. Historians say this lack of haste could be proof that Albinus had the wall built foreseeing it would be wise to have a better fortified British capital when he withdrew most of his troops toward Rome to fight for the throne in the 190s. Historians still ponder why Severus did not knock down Albinus' wall upon his arrival in Britain. The most prevalent theory states that because Severus was more concerned with the northern instability within Britain, he decided to keep the walls intact. This also leads researchers to believe Severus would not have planned a Londinium wall to be built before his arrival in the province because the capital was already a stable area. Although this was a time of economic collapse, monumental sculptures which were made during this time have been unearthed too. 52 massive blocks of limestone built into the fourth-century riverside wall (the wall's extension), some with indented ornaments, were found in 1975; 45 of them in turn came from two extremely large monuments figures containing Hercules, Minerva, Mars and many other Roman deities. Gatehouses were also built at Ludgate, Newgate, Bishopgate and Aldgate. These smaller walls and gatehouses were also completed in the middle of London's recession, when suburbs such as Walbrook and Southwark lay derelict. Governance Under the peace restored by Caracella, both the Upper and Lower provinces began a system of governance that was both similar and distinct. Although the provinces were technically separated, two inscriptions from Geta Bridge and one from Cherterholm mention that the governor of Superior spoke of beneficiarri from his staff on duty in the Lower province. Scholars note that, for a time at least, Britain continued to be governed as a single entity. This means that consular governors like Geta Caesar and Ulpius Marcellus would have been the last two governors before the division. After that, it becomes unclear which specific governors oversaw the Upper Province. It is also unclear what type of general administrative changes happened after the division. The most current theory is that civil jurisdiction over the Lower Province was given to the commander of the Legion at York, but the consular Governor of the Southern Province took command over the entire country when needed. The Governors of Upper Britain were generally
