Castillo de san felipe de barajas: no es una fortaleza fue construida durante un período de más de 150 años protegió los tesoros españoles de los piratas y los invasores ingleses, franceses y holandeses.

We need to select the sentences that are true, and the sentences are:

-Fue construido durante un período de mas de 150 años (Was constructed in a period of time bigger than 150 years)

-Esta en Bogotá (It is located in Bogotá)

-Es una fortaleza impenetrable. (is an impenetrable fortress)

- Fue construido para protejer los tesoros españoles (Was constructed to protect the Spanish treasures)

The construction is located in Cartagena, so the second option "Esta en Bogotá" is wrong, and we can discard it.

The other 3 options are right-ish, for example,it is almost impenetrable, but its enough, so the correct sentences are:

-Fue construido durante un período de mas de 150 años (Considering reparations and such )

-Es una fortaleza impenetrable.

- Fue construido para protejer los tesoros españoles
