The early history of bridge building in the country is attributed to both the Spanish missionaries and conquistadors, who along with their task of converting, pacifying and subjugating souls were also responsible for building communities.

Puente de Isabel II (Province of Cavite)
The bridge was built by Brother Matias Carbonell OSRA in 1857 and situated along Calle Liko and spans the Rio de Imus linking the town of Imus to Bacoor.

Puente Campol (Province of Nueva Vizcaya)
The bridge was built by the Spanish conquistadors in 1739 and situated in the southernmost portion of the Cagayan Valley.

Puente de Barit (Province of lIocos Norte)
The bridge is situated along the Laoag-Bacarra Nacional Road. Nothing much is known about its heritage, but it is a beautiful piece of civic infrastructure that serves as a very important link to towns of north of Laoag.

Puente de Blanco (Binondo)
The bridge is also known as Puente de Binondo, built in 1796. The bridges traverses Calle San Fernando linking Plaza Calderon de la Barca now known as Plaza San Lorenzo Ruiz to San Nicholas district. The Maestro de obras was Policarpio Faxardo with Phelipe de Mesa as sobrestante or
foreman.

Puente de Malagonlong (Province of Quezon)
It is the most spectacular bridge from the Spanish Colonial era. The construction was started in 1841 and finished in 1850. It links Tayabas with the coastal town of Pagbilao, then an important link to the coast.

Puente del Fuerza Santiago (Intramuros)
The construction of the bridge started in 1591 and was completed in 1634 under the direction of Leonardo Iturrino. The bridge was built west of the gate leading to Fuerza Santiago. Today both the moat and the bridge have been fully restored to give visitors a partial glimpse of the history of Fuerza Santiago.

Puente de Mabacao (Maragondon)
The date of construction and the name of the builders remains unknown. It spans a rather wide gorge and is supported by three masonry piers resting on solid rocks.

Puente de Busay (Province of Albay)
The bridge is located along the Guinobatan-Camaiig national road which straddles the border of the two towns overlooking either the majestic Mount Mayon on its eastern side or the spectaculars Busay Waterfalls.

EI Hogar
D. Antonio Melian established in 1910 a building society that issued mortgages called "EI Hogar Filipino." Four years later, in 1904, the four story building of the company, designed and constructed by Irureta-Goyena, was inaugurated on the corner of Juan Luna in Binondo facing the Pasig River. Designed with touches of the French Beaux Arts style, it has an enriched entablature topped with an attic story and a flat roof. It looks deceptively sedate until one enters its discreet entranceway. The double door leads to a center courtyard with balustraded corridors connected by an exuberant Art Nouveau staircase situated along the end of a passageway. With bronze griffins for newel posts and gilt swirling around initialed medallions, the interior speaks of a bygone elegance.

Regina Building
One of the earliest structures made of reinforced concrete, a material introduced during the American colonial period. According to sources, the original three-story building was designed by Andres Luna San Pedro. In the early 1930's it was bought by the De Leon family from the Roxas family and a fourth floor commissioned from architect Fernando Ocampo. The building is one of Manila's architectural landmarks, and is an example of the Art Deco style. Together with the Perez-Samanillo which is right across the street, it establishes a strong presence on the Escolta.

Luneta Hotel
The Luneta Hotel, the only building in Manila with French Renaissance style windows and balconies with cast-iron grills, has been attributed to Andres Luna San Pedro at various times. But what is known is that it was planned and owned by a Spanish architect-engineer, Salvador Farre, who also designed and built Montalban Dam. The Hotel may have been built in 1918 or 1920 when the Americans brought in reinforced concrete that allowed the construction of high rises. An early title to the property from Manila City Hall, dated 1915, makes no mention of the building. In 1922 a mortgage was taken out that was eventually paid off in 1930.

The Hong Kong Shanghai Bank Building
On September 22,1922, the acting Governor-General of the Philippines, Charles Emmett Yeater, spoke at the dedication of the Hong Kong Shanghai Bank's new building on Calle Juan Luna and Callejon San Gabriel in Binondo. Standing on a 10,706 sq. meter lot with five storys of structural steel encased in concrete; its treasury vaults had enclosing walls of 40 inches, including armored walls 20 inches thick and reinforced with two networks of twisted steel bars. The ground floor ceiling was 23 ft high, and the upper floor's ceiling six1een feet high. The architect was an American, G.H. Hayward, as was the contractor, Oscar F. Campbell.

Panqasinan Provincial Capitol
The neo-classical provincial capitol of Pangasinan designed by architect Ralph Harrington Duane, is probably the most famous building dating back from the American colonial period. Easily the most impressive public building in the province, its erection involved meticulous city planning. It formed the centerpiece of a grandiose plan that included the provincial high school and the governor's mansion. It was inaugurated in 1918. The Capitol was severely damaged during the pre-landing bombardment of Lingayen Beach by the American 7th Fleet in January 1945 and later restored.

Metropolitan Theater
The Metropolitan Theater is the most outstanding example of Art Deco architecture in the country. Designed by Juan Arellano in 1931, it stands in contrast to the neo-classical architecture that typifies its adjacent buildings. The facade of the Metropolitan Theater is festive and colorful. It features stylized motifs typical of Art Deco design, but with a uniquely Filipino touch. These Filipino motifs of tropical flowers and fruits ornament the structure's grilles, stairways and wall detailing. The other remarkable features of the Metropolitan Theater are its proscenium-like entrance, window-mural of colored glass. The 4-bay, six story building is crowed by a pair of mansard roofs. On the front French windows open to balconies with cast-iron grills. The balconies are supported by consoles. Amorsolo murals and plaques depicting the muses of Music, Tragedy, Comedy and Poetry adorn the walls of the building. The Metropolitan is in danger of being demolished.

(Uy-Chaco Building) Philtrust Bank Building
Built in 1914 by Samuel C. Rowell, the 6-story Uy-Chaco Building on Plaza Cervantes is considered Manila's first skyscraper. The design is rather electric. However, its
undulating balconies and iron grilles mark it as belonging to the Art Nouveau style, making it Manila's first and last building style. The most striking feature of the building is the projecting turret on its northeastern corner. The rounded corner, emphasized by curving railings, gives the building the appearance of a French chateau. Rising from the eaves is a gabled roof with round clocks instead of windows. The building also features eight distinctly-designed bats, and projecting balconies on the third, fourth and fifth, floors.

Standing at the western entrance of Panguil Bay in Ozamiz City, Misamis Occidental, the Fuerte dela Conception Y Del Triunfo is one of the four oldest surviving stone fortresses in the country today. Named after the Spanish armada flagship "Triunfo", the fort was built in 1756 under the guidance of Juan Nepomuceno Paver S. J. and Fr. Jose Ducos S. J., a chaplain in the Spanish armada who distinguished himself in military exploits during the Misamis Campaign from 1754 - 1755.

Built as defense against Moro raids, almost 250 years ago, the fort was also used as provincial headquarters by the Constabulary during the American period and as garrison of the Japanese Imperial Forces during the Japanese occupation.

It is popularly known as "Cotta" by the local populace and by those in the nearby provinces and cities.

In March 2002, the National Historical Institute declared the Spanish fortress as a National Historical Landmark.

Nestled on the hills in the city of San Fernando is the newly established La Union Botanical Garden. It is about eight kilometers east of the Plaza and about six hour-ride from Manila. It occupies about ten hectares of land owned by the provincial government of La Union.

The Garden was originally conceived by Ms. Mary Jane c. Ortega, now the city Mayor of San Fernando and wife of the then Congressman Victor F. Ortega, Representative of the First District of La Union. Congressman Ortega took the primary responsibility and interest In allocating a portion of his Countrywide Development Fund towards its establishment. Earlier, he made representations with the Provincial Government led by Governor Justo O. Orros, Jr. to set aside ten hectares for the project. the Provincial Board headed by the then Vice-Governor Amparo M. Aspiras passed the resolution which took effect on March 1995.
