German President Christian Wulff visited Mexico's iconic pyramids of Teotihuacan over the weekend.

Wulff, who is on a tour of Latin America that will also take him to Costa Rica and Brazil, visited the pyramids on Sunday with his wife, Bettina, under tight security.

The German president and his wife toured the archaeological zone and climbed the 42-meter (138-foot) Pyramid of the Moon, the second-largest pyramid in Teotihuacan.

Wulff, the youngest president in the history of the Federal Republic of Germany, had to remove his jacket and tie due to the high temperatures at the park.

The 51-year-old Wulff will be received by President Felipe Calderon, who attended the beatification of Pope John Paul II over the weekend at the Vatican, on Monday.

Wulff plans to meet with representatives of human rights groups and will deliver an address at the National Autonomous University of Mexico, or UNAM.

The German president is also scheduled to visit the Mexico City Cathedral and to attend a dinner Monday night hosted by Calderon.

Wulff plans to fly on Tuesday to Silao, a city located 350 kilometers (217 miles) northwest of Mexico City in Guanajuato state, where he will tour a plant belonging to German toolmaker Schaefer Group.

The German president is scheduled to tour the historic downtown of Guanajuato city and then fly to Costa Rica, where he will stay until May 4.
