Yep, they have museums
The museums here get a lot of support from the government. As a result, the prices for admission are really low - often time less than 10 patacas. I will add more here later
Sun Yat Sen Memorial House. A museum dedicated to the man who is called the Father of Modern China, who helped overthrough the Qing Dynasty. This museum is free and close to both the Jardim Lou Lim Ieoc and the Macau Tea Culture House. It is also close to Guia Hill Park. This is worth a visit.
