People of all ages were lined up around the square to pay their respects to the man who so influenced the lives of millions in this Caribbean nation.

"The best tribute to Fidel is to carry on his ideas. He gave his life so that all Cubans could have basic rights, like education and health," said high school student Carlos Martinez, who was standing in line along with a large number of his friends.

Many of those in line held pictures of Castro, while others brought flowers or simply a Cuban flag as a way to show their affection for the late leader.

"I will defend Fidel's ideas and legacy until my last breath, because he was a man that gave our nation and people back their dignity," said Teresita Gonzalez, a public-sector employee.

Others underscored Castro's unique personality, and his impact on global politics and international affairs during the Cold War era of hostile relations with the United States.

"He stood out from the rest of the leaders around the world and turned Cuba into a model of solidarity, social justice and international cooperation," said Sofia Rodriguez.

While Castro passed away at the age of 90 late Friday night, his ideas will endure for many years to come, many of those paying tribute indicated.

"I decided to bring my two-year-old daughter, because they (the children) are the future of Cuba. I want her to see and understand who Fidel was and what she can do to help the revolution continue," said Yanet Ricardo, as she was about to enter the memorial, with her child in her arms.

The tribute will continue through 10 pm Monday, and on Tuesday.

Leaders across the globe have expressed their condolences and admiration for one of the great figures of the 20th century, whose leadership brought unprecedented development to this corner of the Caribbean.
