Learn Hardcore Korean: bakmulgwan ape johyeongmuri isseoyo. - There is a sculpture in front of the museum.

조형물 literally means “sculptural object” or “art installation.” It’s a compound of 조형 (造形, “shaping” or “molding”) + 물 (“object”). Here it refers to a piece of public art or sculpture.

How does 앞에 work in 박물관 앞에?

앞 means “front” and -에 is the location particle. Together, 앞에 means “in front of.” So 박물관 앞에 = “in front of the museum.”

Why is 있어요 used here? What does it indicate?

있다 is the verb “to exist” or “to have.” In 있어요, you have the polite present tense. So 조형물이 있어요 means “there is a sculpture.” In Korean, you always use 있다 when stating the existence or presence of something at a location.

Why is 조형물 marked with -이 (subject marker) instead of an object marker?

Existence verbs like 있다/없다 treat the thing that exists as the grammatical subject. So you use -이/가. Here, 조형물이 is the subject (“the thing that exists”).

Can I omit the subject marker -이 and just say 조형물 있어요?
