The modern building wins few admirers , but there is a free tour ( Sunday and Thursday , 8 : 30 a.m. to 2 : 30 p.m. ) and you can watch the debates ( Monday through Wednesday , 4 : 00 to 7 : 00 p.m. ) . Passports needed for both .
Most people don 't like the modern building , but it 's still open for free tours .
