Seal and flag of Nueva Vizcaya

Original Seal

The dexter part of the seal is divided into three parts:

1. The two bundles of palay over a green field represent the abundant rice supply well-known in the province.
2. The three mountains symbolize the main mountain ranges that surround the province, the Cordillera, the Caraballo, and the Sierra Madre. The white hill (apparently missing in all versions of the seal) represents the Salinas Salt Spring that died out when the 1990 Luzon earthquake hit the province.
3. The two logs flowing over the Magat River indicate a well-established lumber industry of the province.^[1]

The sinister part of the seal contains the historical coat of arms of Biscay before 1986, its namesake. It was the birthplace of Governor-General Luis Lardizabal y Montojo, who ordered the creation of the politico-military comadancia of Nueva Vizcaya.^[1] The four lions in the Biscay coat of arms symbolize the nearly 4 centuries of Spanish rule over the Philippines.

The surrounding ring text reads PROVINCE OF NUEVA VIZCAYA (top), and OFFICIAL SEAL (bottom) separated by two black stars.^[1]

Modified Seal

The dexter part of the seal is divided into 5 parts, listed from top to bottom:

1. The three mountains symbolize the main mountain ranges that surround the province, the Cordillera, the Caraballo, and the Sierra Madre. The white hill, representing the Salinas Salt Spring, is still displayed, even though the springs already died out as a result of the 1990 Luzon earthquake. (present in the original 1917 seal)
2. The two piles of logs (separated from the river), containing three logs each, symbolize both forest wealth and the lumber industry. (present in the original 1917 seal)
3. One cattle, offset to the center to accommodate the capitol charge, represents agriculture. (new element)
4. The two bundles of palay over a green field represent the abundant rice supply well-known in the province. (present in original 1917 seal)
5. The water waves (separated from logs) represent the Magat river. (present in original 1917 seal)

The sinister part of the shield contains a modified version of the Biscay coat of arms, with the border's color changed to red, with the lions' color changed to yellow. The oak tree was replaced by a Narra tree, with the cross and two wolves removed. The center is charged with a profile of the front facade of the Provincial Capitol. The surrounding ring text reads PROVINCE OF NUEVA VIZCAYA (top), and 1839 (bottom) separated by two black circles.
