The view of the Lighthouse on Sunderland South Pier is taken from the south-east. The entrance to the harbour lies beyond the pier-head, to the right, on which a crane, and a capstan used in warping out ships, are perceived. The large D on the fore-topsail of the collier lying within the pier is a distinguishing mark adopted by the owner that his vessels may be more readily known. To the left is seen the higher lighthouse, of stone, which stands on the north pier, on the opposite side of the river.

The erection of a pier on each side of the entrance to Sunderland harbour has been rendered necessary in consequence of the constant tendency of the bar of sand at its mouth to accumulate. The piers, by contracting the channel of the river, have deepened the water, and increased the velocity of the current at ebb tide, which thus scours the entrance to the harbour, and prevents the accumulation of sand upon the bar.
