On Rio beach, a man's home is his castle

RIO DE JANEIRO - With a crown on his head, Marcio Matolias carefully retouches his sand castle, sculpting and smoothing with a shovel as bathers cool off nearby in the suffocating January heat.

They say a man's home is his castle and Marcio has lived in his - albeit made of sand - on a beach in Rio de Janeiro for the last 22 years.

In Barra da Tijuca, a wealthy beachside neighborhood west of Rio, neighbors and friends call him "The King".
