Here Augustus in 34 B.C.planted a 'Colonia Iulia Augusta Emona', and recent work of Dr.W.Schmid has thrown much light on its character.
The colony was in outline a rectangle of nearly 55 acres (480 x 560 yds.), and was divided up into forty-eight blocks by five streets which ran north and south and seven which crossed them at right angles; of these forty-eight blocks some must, of course, have been taken up by public buildings.

They varied in size: the largest as yet planned (II in fig.

25) measured 170 x 195 ft., or 3/4 acre; two others measured 163 x 170 ft.; while one block, which contained one large house not unlike the Silchester 'inn', was 112 x 168 ft.

(Plan, II), and the block next it was a trifle smaller.

None of the dimensions show any trace of the normal 120 or 240 ft.
