14 of the top schools use a huge warehouse called Samba City to build and store floats plus make their costumes and rehearse routines. Cidade do Samba has an incredible one million square feet of space stretching across 14 city blocks. This is a fascinating place to tour. You will hear samba music, marvel at dance performances, watch seamstresses creating intricate costumes and see crews laboring on floats as you walk along a 26 foot high catwalk. So, if you miss experiencing Carnival in Rio, a visit to Samba City is the next best thing. The attraction is open all year.
