[2][3] The name Brunanburh[4] is suggested to mean "Bruna's fortification", with burh being Old English for a fortified place.

[7] An Anglo-Saxon cross, reconstructed from fragments, is in the churchyard of local parish church St Barnabas.

It was hoped that establishing the market in the vicinity of Bromborough Cross would promote honest dealing.

The market cross was the traditional centre of the village and also an assembly point for local farm labourers available for hire.

[10] An increase in traffic passing through the area resulted in Bromborough undergoing extensive redevelopment in the 1930s.

[13] The partially medieval Bromborough Cross, in the old village centre, is a designated Grade II* listed building.

[15] Both Stanhope House and Pear Tree Cottage are Grade II listed and are amongst several buildings from the late seventeenth century that survive in the modern town.

There is one main tier of local government covering Bromborough, at metropolitan borough level: Wirral Council.

The Bromborough ward is generally defined by Stanley Road in New Ferry to the north, the Mersey to the east, the railway line to the west and Acre Lane to the south.

In some cases, including Bromborough, the civil functions were exercised by each township separately rather than the parish as a whole.

In 1866, the legal definition of 'parish' was changed to be the areas used for administering the poor laws, and so each township became a separate civil parish.

[26] Bromborough remained part of the borough of Bebington until its abolition in 1974 under the Local Government Act 1972.

Part of the industry is connected to the former Bromborough Dock and includes a ammonium nitrate warehouse and the main landfill site for the Wirral, now a walkway with views of the river.
