Lou Kau Mansion was built in 1889 for Lou Kau, a wealthy Chinese merchant and prominent Macau landowner. The house shows the plan and detail of a traditional Chinese residence, with courtyards, carved screens, and decorative plasterwork.
It is a small but worthwhile stop near Senado Square, especially for visitors following Macau's historic centre on foot. The mansion gives a quieter counterpoint to the larger churches and forts nearby.
