The two prominent buildings are the Ipswich Post Office (built 1900) and Old Town Hall (built 1861). The Town Hall had its clock installed in 1879. From 1901 until 1912, Ipswich had two clocks side by side in these two buildings, although they were generally showing different times! The Post Office clock was illuminated in 1912 and the Town Hall clock was sold to Sandgate Town Council and was installed in Sandgate Town Hall in 1923.
