The Baza Outdoor Oven is a 20th-century version of a traditional hotnu, or outside oven, on the island of Guam. This oven is located at the end of Beatrice Baza Drive in the village of Yona. It was built in 1952 out of brick and concrete, but is based on traditional forms that have been in use on Guam since they were introduced by the Spanish in the 17th century. It is a barrel-shaped structure about 2 metres (6.6 ft) long, 1.5 metres (4.9 ft) wide, and 1.67 metres (5.5 ft) high. The base of the structure is poured concrete about 0.6 metres (2.0 ft) high, with the vaulted portion about 1 metre (3.3 ft) high. The interior of the vault is made out of heat-resistant bricks, while the exterior is finished in cement. The oven was used by heating it until the bricks were white, after which the burning materials were removed, the food to be cooked was added, and the main door was closed. This oven is large enough to roast four pigs. The oven was listed on the National Register of Historic Places in 2010.

The Ylig has two tributaries, the Tarzan and the Manengon rivers.

The Light Model Tank No. 95 is a relic of the Japanese occupation of the US territory of Guam during World War II. It is the remains of a Type 95 Ha-Go light tank, that was in a highly visible location on Cross Island Road when it was listed on the National Register of Historic Places in 1979. At that time little more than the tank body remained, its turret and gun having been removed and sold for scrap. It was at that time one of three such tanks known to survive on the island.

Guam Adventist Academy (GAA) is a K-12 private school run by the Seventh-day Adventist Church in Guam and the Seventh-day Adventist Guam Micronesia Mission, in Yona, Guam. The school's Windward Hills campus is across the street from the Windward Hills Golf Club. In 1949, Pastor Dunton founded what would become the GAA in Dededo, with an enrollment of 26 pupils. The second GAA school in Talofofo was opened in 1951. By 1957, the two schools merged into one K-12 institution, located in Agaña Heights. In July 1963, the institution secured what would become its current location in Windward Hills. In 2007, the school had about 100 students. As of 2010, the school combined the high school graduation and the eighth grade promotion exercises into a single ceremony.

The Tokcha' Pillbox is a Japanese-built World War II-era defensive fortification on the island of Guam. It is built on a limestone terrace on Togcha Point, about 1 mile (1.6 km) north of the Togcha River and 0.7 miles (1.1 km) south of the Ylig River. It is set in a depression excavated from the limestone about 15 metres (49 ft) inland from the high tide land and 1 metre (3.3 ft) above sea level. It is a roughly rectangular structure built out of steel-reinforced concrete filled with coral and beach aggregate. The entrance is on the north wall, sheltered by a wall of coral blocks, and the gun port is on the south wall. This structure was built under the direction of the Japanese military during their occupation of the island 1941–44. The pillbox was listed on the National Register of Historic Places in 1991.

The Pago Bay Japanese pillboxes are a pair of World War II-era coastal defense pillboxes located on the shore of Pago Bay, located on the central east coast of Guam. Built out of steel-reinforced concrete mixed with coral stone, these two structures were built by Japanese defenders during their occupation of the island between 1941 and 1944. They were listed on the National Register of Historic Places in 1991 as Pagu' Pillbox I and Pagu' Pillbox II. Neither of these would have seen substantial action during the 1944 liberation of Guam, whose military activities were focused on the western, central, and northern parts of the island.
