山上有一座塔英语

两种翻译任选：There is a tower on top of the hill.On top of the hill is a tower.

There is a tower on the top on the mountain

There is a tower on the peak.

此处用at，at和on的区别是：at表示一个点，像你的句子中的山顶，而on表示一个面，还是你的例子，如果是在山上，就可以用on，表示在山上，不表示具体点。

at 山的顶端是山的一部分

There is a tower on the top of the hill.

The top of the hill stands a tower, its history can be traced back to thirteenth Century. With full inversion structure
