While the economy is dominated by the federal government, and service industries that support government workers, Ottawa has had several other important industries. Before becoming the capital, Bytown was a centre of the logging industry. The lumber industry remained prominent in Ottawa until the early twentieth century. The lasting legacy in Ottawa are the mansions and buildings constructed by the lumber barons who made up much of the economic elite of early Ottawa. Most notable was John Rudolphus Booth, who commissioned several prominent structures from architect John W.H. Watts. While the lumber and pulp mills disappeared from Ottawa in the early twentieth century, Hull across the river remained an important industrial centre and its waterfront was largely industrialized. Most of those factories have now disappeared, but a few remain. Including the E. B. Eddy Company plant directly across from the Parliament Buildings. Ottawa itself does today have some industrial areas, mostly clustered around the rail lines in the Cyrville and Tanglewood areas south of the core. There is virtually no heavy industry, and most of the industrial buildings are warehouses serving as transshipment points for goods made elsewhere.
