He visited Britain, where he crushed the inroads of the Caledonians and built a fortified line of works, known as the PICTS' WALL, extending from sea to sea.

The remains of this great work are still to be seen, corresponding nearly to the modern boundary between England and Scotland.

He also visited the East, where the Jews were making serious trouble, and completed their overthrow.
On his return to the city, the Emperor devoted himself to its adornment.
Several of his works, more or less complete, still remain.

The most famous of these is the MAUSOLEUM (Tomb) OF HADRIAN, now known as the Castle of San Angelo.
Hadrian was afflicted with bad health, suffering much from diseases from which he could find no relief.

On account of this, and to secure a proper succession, he associated with himself in the government TITUS AURELIUS ANTONINUS, and required him to adopt Marcus Annius Verus and Lucius Verus.
